Hilda, It seems the families we are searching for are linked. Hugh Hall Allan b. app. 1851 was the son of William Allan and Jane Allan, on the 1901 census for Dennistoun, Glasgow it says Hugh was born in Cambuslang. Hugh Hall Allan's wife was Mary Curtis b. app. 1854. Her parents were Joseph Curtis and Agnes Moffat. Mary was born in Ballantynes. Their children were William b. app 1876, Mary b. app. 1879. and Joseph Curtis Allan b. app. 1883. Agnes Moffat Curtis was born about 1830. Mary(wife of Hugh) had a sister Janet Curtis. Joseph Curtis Allan married Ann Harvey Maxwell Graham in 1911 in Glasgow. I'm trying to find out now about Ann's family, especially her brother John Maxwell Graham born January 19th, 1883 in Glasgow. Hope you can help!
