I see some records on the marriage of these two, but not in my records. I would love to connect my Kemp lines to Ireland if I could for I know that there were records somewhere that I was reading about Kemp's in Ireland but the names didn't connect with mine at the time, now I know they do but for the devil of me I cannot remember where I saw those notes.
Your William, do you have any parents for him? And siblings at all? Any records of where he resided? William was such a very popular name for the Kemp family lines. I've searched for any Quinlanes since they usually married back and forth during those times, but I have no Quinlanes.
I do have membership right now in Ancestry.com and see many with this couple but none shpw parents for either and alot are unsourced.
Let me know if I can help further.
