The Oxfordshire Surname Interest List, or OXSIL, is an online resource to help genealogists and family historians find others researching the same surnames in the towns and villages of the County of Oxfordshire, England.

OXSIL is maintained in close collaboration with the Oxfordshire Family History Society.

If you submit your surname interests to OXSIL, you are essentially agreeing to receive messages from others with the same surname interests and to share information with them.  You should be aware that researchers who contact you are more likely to ask for your help than to offer theirs.

Making Contact

If you find a surname of interest and you want to contact the researcher, just click on the highlighted user name to the right of each surname and put that person’s OXSIL user number in the subject line so we know who to forward your message to.

To make it easier, each user profile includes a ready-made contact line that you can copy and paste into the contact form. 

We will never share your details with any third party, even other users. You will be able to see the e-mail address of the people trying to contact you, but they will not know yours until you reply to them.

Monthly Newsletter

As well as forwarded messages, as an OXSIL user you will receive a monthly message from us with the names of recently-added surnames and any admin information of importance to do with your membership, such as any significant changes to the website or how best to use it.

E-Mail Addresses and Spam

E-mail addresses provided by OXSIL users are not published on this website, so you will not receive spam if you decide to register your surname interests on OXSIL. Messages to OXSIL users are routed via the website maintainers, who undertakes to forward messages to users within a reasonable time, generally within 24 hours.

For OXSIL to function, it is essential that your e-mail address is correct and up-to-date. If it is determined that your e-mail address does not work, your surname interests and contact details will be removed from OXSIL.


The Oxfordshire Surname Interest List covers the modern County of Oxfordshire, i.e., it also includes that area of Berkshire transferred to Oxfordshire in the local government reorganisation of 1974. If you are not sure whether the parishes you are interested in are covered, please check the Parish Register Coverage Map (courtesy of the Oxfordshire Family History Society).

A subset of the OXSIL website, the OFHS Surname Interest Directory, is available for members of the Oxfordshire Family History Society (OFHS) to register all their surname interests, including those outside the County of Oxfordshire. Non-Oxfordshire surnames listed in the OFHS Surname Interest Directory are not included on OXSIL.

Additions and Updates

If you want to add new surnames to OXSIL, please use this form to do so; if you are a member of the Oxfordshire Family History Society, entering your membership number will expand the form, allowing you to to add non-Oxfordshire surname interests to the OFHS Surname Interest Directory at the same time. If you want to make changes to existing surname entries, please include a note to that effect in the notes field.

If you already have surnames on OXSIL, please use the same form to register any new ones; if you want to register a new e-mail address, please tell us what your old address was.

Contact and Feedback

We hope we’ve covered all the essentials above. If we have missed something or you’d like to provide feedback, you can reach us via the Contact form above.

Thank you.
