In the 1881 Census for St.Andrews I found the following: George Aitkenh.34 Freestone Quarryman b.Strathkinness,Fife Euphemia "w.36b."" David"s. 6b."" Thomas"s. 4b."" Lizzie"d. 4 (twins?)b."" Catherine"s. 2b.""
I don't think George's age is quite accurate, but I think this is the right family as Thomas has the middle name Rodger in the IGI. Also Euphaemia's parents are David Rodger and Euphemia Aitken. Euphemia's ch.18/9/1844 St.Andrews. They married 4/4/1870 in Dundee, Angus. Don't be misled though by this as this is a short journey across the Firth of Tay. I can't find any trace of George in the IGI, but that is not unusual. Is this perhaps who you are looking for?
