Hi Linda, I have a connection to the Elliot family that you are researching. I am descended from Isabella Elliot, daughter of John Elliot, shepherd, and Margaret Hart.
Isabella married a Robert Elliot and they also had ten children. They lived at on a farm at Cavers Mains. We visited the farm and the nearby church a few years ago.
John Elliot d. Cavers Mains 11 Nov 1869, aged 80
Margaret Hart d. Shiplawcross 17 Jan 1840/49?, aged 47
I think we have the same list of offspring that you give and have birth years for them and dates of death for a couple e.g.
Janet Elliot ,their daughter, d. Dryburgh 22 Mar 1867, aged 33
George Elliot their son, d. Newcastle 10 Jan 1872, aged 41
Please let us know if you would like more information. For example...
we can go back a generation on John Elliot and two generations on Margaret Hart.
we have John Elliot's family bible, various samplers made by some of the girls and an early phto of Cavers Mains.
My connection is that my Margaret, a daughter of Isabella and Robert Elliot, married my gGrandfather Robert Douglas on Xmas day 1874.
Looking forward to hearing from you.
Andy (and Steph) Douglas
(and we have to thank Steph - she is the one who has put in a lot of hard graft to get the information over the years.)
