The furthest I've gone back so far is Thomas Hannabuss, born around 1817 in Butterleigh. He went on to marry Jane Baker, born around 1818 in Cullompton, in the summer of 1843 in Tiverton, before moving to London where my great-great grandfather, Tom, was born in 1867.
Although, as ever, the 1841 census is a little hazy there is a Philip Hannabuss listed in Butterleigh with two children, Henry born in 1816 and Mary born in 1821. Thomas isn't listed but I suspect this may be his father and siblings. If correct, his mother's name is Mary Baker - she and Philip married on 19th March 1808 in Cadbury.
Philip is listed in 1841 as being born circa 1781, but I can't find definitive records to confirm this and/or who his parents are. If anyone has any further links, I'd be extremely grateful.
