When searching for ancestors by last name and you can't find them, try using different vowels. If there are a lot of them, use the ? in place of one vowel or * if you think there will be two or more vowels in a row.(!). Example:
Mowat could be:
Mowet
Mowit
Moit
So, search for them like this:
M?w?t
M*t
Mowat could be:
Mowet
Mowit
Moit
So, search for them like this:
M?w?t
M*t
