I don't have very much info on the Wimsey family. This is what I have:
My great grandfather was Thomas Joseph Walsh(1857) and he married Bridget Wimsey in 1882 in Tubbercurry Co Sligo. The marriage was witnessed by Edel Brennan and Catherine Brett. Bridget's father is listed as Peter. Thomas' father is listed as Michael.
I hope for more info someday. Do you have connections to this info?
