My ggg grandfather John Walker was born in Selkirk in 1812 and married Mary Mien on 12/06/1835 in Selkirk. She was born 1806 in Melrose, Roxburgh. Their children were Andrew b1837, William b1838, George b1840 and Jessy b1845. I am looking for death records for John Walker and Mary Mien and any information on their parents.
