My 4 times gt grandfather was born circa 1779 Tyan/Tynan Armagh, That is from Census forms in Airdrie in Scotland where moved with his family. His wife was Margaret Henthorn born 1792 and died 13 jan 1857 in Airdrie in Lanarkshire. Her death certificate states father Thomas Henthorn mother unknown. George's father is listed as John Fleming Farmer deceased no mother mentioned. Henthorn is quite an unusual name. Is it local?
