Bernard McMillan Greenock Police Officer

I am looking for descendants or relatives of Bernard McMillan who was born in Ireland about 1840 but moved to Scotland and was living in Greenock, Renfrewshire between 1881 and 1897. He was married to Jane Simpson (born about 1830 according to the 1881 census) and they had 2 chidren that I know of, Mary McMillan (my great-grandmother born about 1866/7) and John McMillan. They lived at both 21, East Shaw Street and 17, Lyle Street in Greenock.

If anyone has any information on this family please let me know

Peter
