I have been keeping an eye on this thread as I have an interest in the Langmaid family in Lansellos/Polperro area. It is well worthwhile contacting the Polperro FHS. I did and in my letter box today (in australia) was a family tree of Langmaids (of era that was confusing me) sent by the FHS secretary and editor. All from their databases. Haven't had a chance to have a really good look ...... But there is a John langmaid bap 25 may 1795 Lanteglos, son of John langmaid and Mary Thomas. John langmaid senior (bap. 22 jul 1768, died 24 April 1838 in trewen, Lansellos) was son of Henry langmaid (bap 12 feb 1733 Lansellos) and Elizabeth soby/soady.
Are any of these johns yours?
