Hi Bob
I don't know where John Boag came from but he married Margaret Williamson who was born in Strathbrook, Uphall in 1782 and died in New Monkland in 1860 and was buried in the East Chapel Churchyard. Unfortunately, I have been unable to verify this as the info came from someone else. They had 10 children - John, James, David, Agnes and Margaret who were born in Uphall; Thomas (2) & William born in Airdrie and Mary and Catherine born in New Monkland.
Their son, James, was born in Strathbrook, Uphall about 1804 although I have failed to find his birth records and he died in 1875 in Gartgill, Lanarkshire. He married Jane Nielson in 1829 in New Monkland. Jane (I think) came from Carnwarth, Lanarkshire.
They had 2 sons that I can find, John and Alexander who was born in 1832 in New Monkland and died in Norwich. He married Elizabeth Robb in 1853 in Gartcosh, Glasgow. He worked as a locomotive fireman at Gartsherrie in 1853 and in 1861 lived in Gartgill Cottage, Old Monkland.
My line follows Alexander who moved with his family to Norwich in about 1862, 4 of his children having been born in Scotland and a further 4 being born in Norwich.
I have been trying to further my information for some years now with no success and if there is any connection with your Boags which would help I would be extremely pleased and grateful for details.
