I also have Wilkinson and Smith in Hull. Ken.
OK since a few people have said that they have WILKINSONs in Hull, I am going to list here what I know so far of my WILKINSON line in Hull, I should have more soon with the arrival of a marriage certificate, but maybe all of us can keep each other's e-mail addresses and keep each other in touch as we find new information :-) Right now, I have Harry WILKINSON, b. 1820's in Hull His family lived in the Hedon Road, Marfleet area. He had a brither William, probably others also. His father worked on barges. He was a sailor and in the army, Essex Regiment. He married Gwendoline ANTHONY in Hull in 1944. They lived in West Stockwith Notts, (about 6 miles from gainsborough, lincs), had two children, but Harry left around 1950-54. If any of this rings a bell I would love to hear from you. Kerry
