Hello cousin, well it's a small world. Your Gt Grandfather George Gardiner who was a farmer on Stoneygate had in fact 6 brothers : Thomas, James, Robert, John, Alexander and William. I have the dates of birth of most of the brothers.
Their parents were George Gardiner and Ann Sangster.
George(senior) would be your Gt Gt grandfather and he was my Gt Gt Gt grandfather.
Alexander (Sandy) was my Gt Gt grandfather and many of my relations are in fact from Dyce.
I havent got any further back than George (senior) and Ann Sangster but I'm working on it.
Give me an e-mail at firstname.lastname@example.org
and I can pass you some of the details I have.
