I think this James Allan is my Gr Gr Grandfather. His date of birth 20 Dec 1856. Born (my grandma is pretty sure) in Airdrie. He had a son Robert MArshall Allan (others as well) (in Australia) James left Scotland and came to Brisbane Australia and married Elizabeth Stark. He went into business with her brother and formed Allan and Stark.
before he left scotland he worked in Glasgow at a drapery firm. His father was a farmer in Airdrie. I am reasearching this family and we are off to Scotland next year so hope to meet any 'relies'! or see where our family came from.
