I came across a James Kinkead in County Cavan, Ireland who was married to a Jane who previously held the surnames of Hill, Good and Nesbitt. It appears that her maiden name was Nesbitt and she was then married twice before marrying James Kinkead. This was in 1757. This is perhaps significant because of these surnames seem to tie to some Colonial Kincaids as well. I'm sure some of you American researchers could recall them quicker. Best wishes! Peter
