Been there and done that.

Havent got a dob. Two lots of years as when she died she was 5 years older than should have been . Her name was Catherine Reid and their is umpteen in Scotland. Born either 1829 or 1834.
Thought if I
found the ship I could narrow it down to which one to look for. My Nan has been very accurate on all the verbal info I gleaned from her in relation to her dad's side, have to believe from her maternal side she was also accurate

When she married in 1862 in Tassie the marriage certificates were lacking in parents, dobs etc.
