George Calvert born in 1779
I am looking for information about a George Calvert born in 1779 in Rockcorry, Monaghan, Ireland. He emigrated to America in about 1800. I think he likely went to New York and then Pennsylvania as that seems to be a common travel route for the Irish at that time. He had two children born in the United States Edward (1803) and George (1804). In 1805/06, he moved to Ontario, Canada where free land was being offered. I have quite a lot of information about him in Canada where he had eleven more children with a woman called Martha Hopkins born in New Jersey. He fought in the war of 1812 and had two or three more wives after the death of Martha. He died in 1857.
I would like to find out if there are possibly any church records in the Parish of Ematris that might confirm his birth or even his existence in that Parish between 1879 and 1800. It is possible that he married before leaving Ireland although not likely. I would like to know if there is any evidence of any other Calvert families living in Ematris during 1879 and 1800 and general historical information such as the most likely port of departure from Ireland and whether or not (in 1800) all ships would have gone via a port in England. Also of interest would be anything that was going on in the area in 1800 that would have encouraged him to emigrate?
