Hello
Noticed your interest in the surnames Donaldson, Ramage and Cornwall. I have all three names in my family tree. John Donaldson married Mary Ramage in 1811 Edinburgh, their daughter Janet Donaldson born 25 June 1829 in Temple, Midlothian, married Richard Cornwall (born 1826 in Temple) on the 24 June 1849 in Temple, their son John Cornwall (born 1855 in Borthwick) married Euphemia Peacock in Dalkeith 1875, their daughter Janet Donaldson Cornwall (my materal grandmother) married John Seath (my maternal grandfather).
Does this information have any connection to your family tree.
Best regards, Maggie
