Hello, Someone just told me about a book which is available at Google / Books: "Names of Irish Passengers to America: Over 7,000 with Dates, Ports and Ships ...." by O'Laughlin ... I found out it has 3 HENDERSON names mentioned where they left County Sligo, Ireland: James HENDERSON going to Newport, RI, in 1811 William and Helen HENDERSON going to New York in 1815 Robert and Margaret HENDERSON going to New York in 1816. These people were "coming to America" only about 8 to 12 years before my ancestors, William and Mary (KERR) HENDERSON, left County Sligo in 1823 or 1824 and went to Canada. (And, William's older brother, Samuel HENDERSON, and his wife were with them.) I was just curious if there could be some connection between these families. Also, another book on-line at Google / Books has a title which starts out with: "History of Argenteuil County ......" That is where the HENDERSON / KERR family group settled in 1824. (Province of Quebec - part north of the St. Lawrence River.) I had seen the 2 paragraphs which mention my 2 ancestors before. But, this time I noticed something I hadn't remembered. It said, "William Henderson came from the Parish and County of Sligo, and settled here in 1824. .... He lived here until his death in 1870. He had 14 children ...." None of the researchers knew which town or parish the HENDERSON's were living in in County Sligo. I had guessed the Calry Parish in the northern part of the County. But this says he was in the Sligo Parish. I'm assuming that it means Sligo Town. However, some other researchers and I paid a fee to the "Sligo Research Centre" a couple of years ago, and they could not find the names in the records they have. (I don't think they really tried.) My other ancestor in the group was Patrick KERR and his wife, Elizabeth (KERR?) KERR. Perhaps the KERR's were in the Calry Parish and the HENDERSON's were in the Sligo Parish. The 9 people in the group were born in the 1780 to 1805 timeframe in County Sligo. Betty (near Lowell, MA, USA) My gr-gr-grandparents, Robert KERR and Elizabeth HENDERSON were born in Argenteuil County, P.Q., in 1827.
