Hello flora
Is it possible you have posted the wrong year of marriage for Robert and Agnes Kirkland? I didn't try and track it down but I did notice there is an interesting entry in the 1881 census that looks like it could be them with a full family....
They are found at 31 Clunes Vennel,Newton On Ayr, Ayr, Scotland GROS 578 ED 14 p 27
The household consists of Robert LEES age 48 b. Prestwick, Ayr, Scotland and he is head and had occupation of Pilot. His wife is Agnes Kirkland LEES age 38, b. Prestwick, Ayr, Scotland.
Children are as follow:
Mary LEES age11 b. Prestwick, Ayr, Scotland
Robert LEES age 8 b. Ayr, Ayr, Scotland
John M. E. LEES age 6 b. Ayr, Ayr, Scotland
Agnes B. K. LEES age 4 b. Ayr, Ayr, Scotland
Marion LEES age 2 b.Newton, Ayr, Scotland
Rosanna LEES age11 m, b. Newton, Ayr, Scotland
Hope this is your family!
Best wishes
