I am looking for a the Michael Cull family who supposedly lived in Cork County, Ireland. Michael was born about 1800. He married Mary McDonald about 1818. They had 18 children, but only 4 lived so far as we know. They immigrated to the USA between 1838 and 1847 where their last child, a dtr, Mary Lucretia was born in New York. Their oldest son was James born about 1820 in Ireland. Another son David was born in Ireland 1838. Of the 18 births,these three children lived to maturity. The family was Catholic. The family legend tells us that James was a lawyer who married a socialite from New York. We cannot find Michael and Mary in the census in the USA which is puzzling. Mary died in 1851 in New York, we are told around New Rochelle, but we can't prove it. We do know that her daughter Mary Lucretia went to live with Uncle James after the death of her mother and later went to California and married in 1869. Supposedly after the death of her mother, her father Michael and son, David (both widowers) went to California to Humbolt County. We verify David being there in 1870's to his death in 1894 in Yuba, CA, but haven't been able to verify Michael. Our biggest question is trying to find immigration records showing any helpful information. It is very curious why a prominent lawyer (James Cull) can't be found in New York either. We don't know if maybe James came over first with relatives and friends and then Michael and wife with David came later. Any help with immigration records would be really helpful.
