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 surname interests listed in the OFHS Surname Interest Directory are not included in OXSIL.

If you are a member of the Oxfordshire Family History Society and want to add new surnames to OXSIL and to the OFHS Surname Interest Directory, please do so here. 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.
