Jean- Thanks for the prompt reply. On the surface there doesn't seem to be a fit but you never know.
Gavin was born 1804 in Bothwell, Lanark, Sotland and married Agnes Russell in Glasgow. They immigrated to Ontario (Seneca Twp) in mid 1840s and were original land patentees. Two children born in Scotland (Janet and James) and five in Seneca TTwp, Ontario (William, John, Mary, Agnes, and Margaret Ellison)
James and John died in Seneca 1916 and 1879 respectively. William, our ancester, had 3 children 1870-1873 but unknown if he died or abandoned family then. Daughters were in Ontario but the Whitlaw name would of course not continue.
