I discovered a few "black sheep" family members when searching my ancestry. That happens.

I also went to a site: Olive Tree Genealogy and read the Ships Passenger lists of immigrants entering America for more help. I found several groups of relatives that entered at different dates, ports and places of departure (then did the math) on different reasons for leaving the Islands, be it wars, famine, the Clearance, indenture servitude, etc.

Good hunting.
