 In another version of her daughter's obituary, her name is listed as Kelley.
 it says:
   Mrs. Vincent was born in Daysville, August 25, 1854, a daughter
   of James and Martha Kelley Thompson.  Her father was born in Eng-
   land, her mother in Ireland.  In coming to this country the mother, then
   a little girl was the victim of a shipwreck off the coast of Cape Cod.

   drowned.  It was in Canada that Martha Kelley met James Camp-
   bell (sic) and married him.
