Hi, I am tracing the name in 2 places Norfolk where a William Blackburn married Ann Bishop in Yarmouth & had many kids, this is all the info I have on this one. One child was called Elizabeth b. 1812 in Yarmouth. The second one is a William Blackburn married a Elizabeth Campbell in Liverpool somewhere. They had a few kids one called William b. 1859-60 in Liverpool. These 2 William's are not the same people. One is my husband's the other is mine. Mine comes from Norfolk.
