My gggg grandad was John Thom who married Helen Barclay
John Thom and Helen Barclay's son James Thom married Jane Mackie - he was my ggg granddad
James Thom and Jane Mackie's son was David Thom - he was my gg granddad who married in 1861.
I believe David's brothers and sisters were John, Andrew, Charles, William and Jane (Jean).
I hope this has helped and look forward to hearing from any related family regarding the above
