Thank you Lyn,
That helps, Yes, this certainly is the right family. I have found a record of them arriving on the ship CHESTER at New York in 1843. Most of the children are on board (Christ. Russell 50, Mrs. 49, Sarah 19, Ann 17, Christ. 15, Rebecca 11, David 9). William, Mary, & Hannah are missing. I now know that William stayed in England. After arrival in NY, the family must have come up to Canada. Christopher's IGI birth date matches EXACTLY with what is on his stone in Ontario, so because of that, and a few other reasons, I am sure that my Ontario Christopher & Rebecca GGG Grandparents are the folks from Kirkbymoorside. What puzzles me is that of all those children I can find only son David, my GG Grandfather, in Ontario. He is buried with Christopher & Rebecca at Houghton. Puzzling. Perhaps not so much if one considers that aside from David there was only one other male (Christopher); all the rest were female and probably have different names. And these are the early days of few records.
Thanks for giving this some thought! And I appreciate the information about extensive emigration from the area in the 1840s.
