This list is arranged hierarchically, in keeping with the overall GENUKI structure. Most of these mailing lists are run by Rootsweb and Yahoo. Most lists have an open subscription policy, but those of family history societies generally accept subscriptions only from members, though the list archives are usually accessible to all.
Note (Dated 11 Jul 2016): Rootsweb's links to its mailing list archives are currently failing.
GENUKI is grateful to the late John Fuller who from 1995 until his death in June 2009 maintained web pages with details of genealogy mailing lists and who kept GENUKI informed about the creation of new mailing lists covering the United Kingdom and Ireland. John's pages are now maintained by Linda Lambert and Megan Zurawicz. Information on new mailing lists is posted by Megan Zurawicz to the NEW-GENLIST mailing list, from which details of those relating to the British Isles are taken for inclusion in this page.
