Lisa, the only thing I have on Donald is the following:
He was born in 1839 in Ontario, the son of Donald and Etta Cattanach (about whom I have lots).Donald was a wheelwright and in the 1871 Census was at Wolfe Island and he belonged to the Church of Scotland.
Hannah is buried in Horne Cemetery, Wolfe Island
That's it, I am afraid.
If you have any more (marriage for Donald, etc;) I would love to hear from you.
