I am looking for any information on William Shaw (b.~1810) and Sarah McGill (b.1828-1833). I cannot find birth records, a marriage certificate nor any immigration records. They first appear on the 1861 census in the Guelph area with William's place of birth being listed as England and Sarah's as Ireland.
They had 8 children, all born in Wellington County (as far as I know):
David Bailey Shaw (b. 1855) married Isabella Ann Evans
Joseph Shaw (b. 1856) married Teresa Bard
Jane Shaw (b. 1859) married Arthur Williams
William Shaw (b. 1861)
George Shaw (b. 1862)
Roland Shaw (b. 1868) married Alice Maud Pearson
Elizabeth Shaw (b. 1869) married William Gilliam
Benjamin Franklin Shaw (b. 1872) married Effie ?
Any and all information is appreciated.
