Hello Cathy, Just trying to help. Were you able to find your Lumsden's in the census for Richmond, Va,for 1880 and 1900..? I believe I found them in the above census. Acc to census 1900 they arrived in the USA in 1873. You never mentioned any children. Did they have children= Margaret. George. James. + about three others? Did James b.1879 marry a Cora? Did George b 1876 marry a Bessie?
I think that your William Lumsden born Dec, 1844 in Berse, Aberdeenshire, Sct, was the son of William and Margaret Lumsden, who married 26th April,1835 in Berse, Aberdeen, Sct.
