Exhibit 10.1

EXHIBIT A-1

FORM OF EFSI VOTING AGREEMENT

This VOTING AGREEMENT (this “Agreement”) is made and entered into as of September [●], 2026, by and among John Marshall Bancorp, Inc., a Virginia corporation (“JMSB”), George Sub, Inc., a Virginia corporation and wholly owned subsidiary of JMSB (“Merger Sub”), Eagle Financial Services, Inc., a Virginia corporation (“EFSI”) and the undersigned shareholder [and director][and executive officer] (the “Shareholder”) of EFSI in the Shareholder’s capacity as a shareholder of EFSI, and not in his or her capacity as [a director][an executive officer] of EFSI.

Preamble

Concurrently with the execution of this Agreement, EFSI, Merger Sub and JMSB are entering into an Agreement and Plan of Merger, dated as of the date hereof (as amended, supplemented, restated or otherwise modified from time to time, the “Merger Agreement”), pursuant to which, among other things, EFSI will merge with and into Merger Sub (the “Merger”), with EFSI as the surviving corporation in the Merger (sometimes referred to in such capacity as the “Intermediate Surviving Corporation”) and immediately thereafter the Intermediate Surviving Corporation will merge with and into JMSB, with JMSB as the surviving corporation (sometimes referred to in such capacity as the “Surviving Corporation”) (the “Holding Company Merger”).

Simultaneously with the Merger, Bank of Clarke, a Virginia state-chartered bank and wholly owned subsidiary of EFSI (“Bank of Clarke”), will merge with and into John Marshall Bank, a Virginia state-chartered bank and wholly owned subsidiary of JMSB (“John Marshall Bank”), with John Marshall Bank as the surviving bank (sometimes referred to in such capacity as the “Surviving Bank”) (the “Bank Merger,” and together with the Merger and the Holding Company Merger, the “Mergers”).

As of the date hereof, the Shareholder is [a director][an executive officer] of EFSI and has Beneficial Ownership of, in the aggregate, those shares of common stock, par value $2.50 per share, of EFSI (“EFSI Common Stock”) specified on Schedule 1 attached hereto. By virtue of the Merger, each share of EFSI Common Stock will be converted into the right to receive 2.00 shares of JMSB Common Stock (as such term is defined in the Merger Agreement), and therefore the Mergers are expected to be of substantial benefit to the Shareholder.

As a condition and inducement to EFSI, JMSB and Merger Sub entering into the Merger Agreement, EFSI, JMSB and Merger Sub have required that the Shareholder agree, and the Shareholder has agreed, to enter into this Agreement and abide by the covenants and obligations set forth herein.

Other individuals, as a condition and inducement to EFSI, JMSB and Merger Sub entering into the Merger Agreement, will enter into and abide by the covenants and obligations set forth in substantially similar voting agreements.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties, covenants and agreements herein contained, and intending to be legally bound hereby, the parties hereto agree as follows:

“Transfer” means, with respect to any security, the direct or indirect assignment, sale, transfer, tender, exchange, pledge or hypothecation, or the grant, creation or suffrage of an Encumbrance in or upon, or the gift, placement in trust or the Constructive Sale or other disposition of such security (including transfers by testamentary or intestate succession or otherwise by operation of Law) or any right, title or interest therein (including, but not limited to, any right or power to vote to which the holder thereof may be entitled, whether such right or power is granted by proxy or otherwise), or the record or beneficial ownership thereof, the offer to make such a sale, transfer, Constructive Sale or other disposition, and each Contract, arrangement or understanding, whether or not in writing, to effect any of the foregoing.

No failure or delay by any party hereto in exercising any right, power, remedy or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any right, power or privilege.

5.9.            Enforcement of Agreement. The parties hereto agree that irreparable damage would occur and that the parties hereto would not have any adequate remedy at law in the event that any of the provisions of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof (including the obligations under Section 2.1) in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at Law or in equity. Each of the parties waives (a) any defense in any action for specific performance that a remedy at Law would be adequate and (b) any requirement under any Law to post security or a bond as a prerequisite to obtaining equitable relief.

5.10.        Severability. Any term or provision of this Agreement that is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable. In all such cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision that, insofar as practicable, implements the original purposes and intents of this Agreement.

5.11.        Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any party hereto without the prior written consent of the other parties. Any purported assignment in contravention hereof shall be null and void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and permitted assigns.

5.12.        Third-Party Beneficiaries. Nothing in this Agreement expressed or implied, is intended to confer upon any Person, other than the parties or their respective successors, any rights, remedies, obligations or liabilities under or by reason of this Agreement. The representations and warranties in this Agreement are the product of negotiations among the parties hereto and are for the sole benefit of the parties. Any inaccuracies in such representations and warranties are subject to waiver by the parties hereto in accordance herewith without notice or liability to any other Person. In some instances, the representations and warranties in this Agreement may represent an allocation among the parties hereto of risks associated with particular matters regardless of the knowledge of any of the parties hereto. Consequently, Persons other than the parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date. Notwithstanding any other provision hereof to the contrary, no Consent, approval or agreement of any third-party beneficiary will be required to amend, modify or waive any provision of this Agreement.

5.13.        Expenses. Each of the parties hereto shall bear and pay all direct costs and expenses incurred by it or on its behalf in connection with the transactions contemplated hereunder.

5.14.        Efforts. On the terms and subject to the conditions of this Agreement, the Shareholder agrees to execute and deliver such additional documents as JMSB may reasonably request and use its reasonable best efforts to take, or cause to be taken, all appropriate actions, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the transactions contemplated hereby as promptly as practicable. Without limiting the foregoing, the Shareholder shall execute and deliver to JMSB and any of its designees any proxies reasonably requested by JMSB with respect to the Shareholder’s voting obligations under this Agreement.
