I have been trying to find a death record for my 3x great grandmother for 3 years now. She was born in1819 in Perthshire perhaps Crieff. She married George Sharp in Auchterarder in 1850.George was a weaver. They had my 2x great grandmother in 1851 in Auchterarder. But i have found out during my research that George re-married in 1855 to an Agnes Richardson and then went onto live in Falkirk until his death.So i guessed that Catherine must have died between 1851 and 1855 but i can find no trace of any death record for her whatsoever. Anyones help would be greatly appreciated as it seems a mystery to me. My 2x grandmother was also called Catherine.
