Jamie,
I'm pretty sure that we are talking the same Thackeray family. George James Thackeray born 1840 married Selina Davis in 1873 and was my great grandfather, and Ernest John Thackeray born 1882 was my grandfather. Is your grandmother Margaret Harrison (Thackeray)? Her father Albert would be Ernest's brother. I think some of the other names on your list are George's brothers and sisters - the only one I know anything about is Jane who was a theatrical costumier and married a comic actor. They had four children and went to America. As far as I know their descendants are still there. Have you managed to trace a connection to William Makepeace? I haven't yet come across anyone who has so would be fascinated to see it! I know there was a Thomas Thackeray who was W M's great grandfather, and had several brothers and several sons. If you want to E-mail me on
julia@mbott.freeserve.co.uk I can let you have more!
