Marion, Unfortunately, Jerimiah is one of my brick walls. I do not have his parents names. His wife's name was Bridget McCormac, born in Ireland, and he had a son Thomas, born in Ireland around 1844. I have two possible brothers, Michael, born abt 1815, who was married to a Bridget (may have married in the US), and John, born abt 1820, who had a wife, Mary (may have married in US).
I don't know if he lived anywhere else in Ireland. I was told many years ago that there was a Baker clan that lived in the county south of Galway that began with an L (Limmerick??).
I have searched the available immigration sites and did not come up with anything. So I am not sure when they came to the US. I suspect it was between 1844 & 1848, as their son Thomas was born in Ireland abt 1844 and John was born in the US in Jul 1848. I suspect they had some money as Jeremiah was a skilled laborer (a carpenter) in the mines here and bought property about 1850 and built 3 row houses, which were just torn down in 2006 (fire hazards).
I do not have any further information. Bob
