Hi Tassie,
I'm not doing research on the family, but there are two births in Scotland for a David Anderson Lawson. One in 1897, one in 1899, but both in Dundee, which makes me wonder if they are both to the same family. This could be the second David in 1901:
Address: 104 Ann Street, Dundee, AngusGeorge Lawson, m, head, 52, assisting Jute amescer, Montrose, Forfarshire
Jane ", f, wife, 35, dressmaker, Dundee, Forfarshire
Mary Ann E ", f, dau., 5, -, Dundee Forfarshire
David A ", m, son, 1, -, Dundee, ForfarshireDavid A ", m, boarder, 22, tile layer, Brechin, Forfarshire
If David or Agnes died in Scotland before 1957, you will also be to get their death certificates, which will give details of their parents.
