I would feel better to see the actual souce of the LDS information, intead of a typed transcription of what seems to be a church record, in St. Paul, MN.
"Born at sea" is in reference to Samuel and not his son. That's what is making me take the transcription with a grain of salt.By the time of the birth of his first son he was 26 years old. It seems odd that a 26 year old man (in 1886) would say he was born at sea, especially when he or his family were saying the he was born in Buffalo ten years later (starting with the 1895 Wisc. Census).
All other records that I can find for him and his family state that my Great-Grandfather Samuel was born in Buffalo, New York.
Sadly, I don't have any names for my Great-Grand father's siblings. There is a family in the 1861 Ontario Canada Census (Nassagaweya, Halton, Ontario, Canada) that fits the decription, with a son Samuel, born about 1859. But he and half of his sibling are stated as listed as born in Ireland (nothing more specific). They are listed again in the Ontario 1871 Census, with Samuel's mother already passed away. I need to find out if the actual 1886 church entry for his son Martin William O'Neill still exists and if so where. Perhaps, the St.Paul historical society would be a next step.
Before Samuel established his first farm in Wisconsin in 1893, his second son Samuel Edward O'Neill was also born in St.Paul. By 1910 the family established a second farm in Orchards/Vancouver, Clark County, Washington. If I could find someone in St.Paul to confirm the church record, transcribed by the LDS, there may be other information that wasn't transcribed that could show or dismiss a connections with the O'Neills of Nassagaweya, Halton, Ontario, Canada. Surprisingly, there are no as many Samuel O'Neills, from that time period, as I would have thought. Still, I hate to find myself wasting too much time on a false lead.
For years I had thought that Samuel's fist son Martin, was named William or Bob, but I confirmed beyound a doubt that he was named after his mother's father, Martin Ward.
