I had afew spare credits on Scotlandspeople and found the following. Hope it is of some help.
Roderick Albert McRae married Helen Welsh Seath in 1915 in Auchterderran Fife in the Free Church of Scotland.
His age is given as 26 making his birth C1889
Helen's age looks like 24 or it may be 21 her birth would be C 1901
His parents are Donald McRae and Marion Baxter?
Her parents are John Seath & Helen Welsh.
You should be ablt to find their births on SP.
Good luck with you search.
