Not finding ANYTHING at all to connect these people with Indiana--which is not necessarily to say they weren't here; but not looking likely.
I found a couple of entries on Ancestry that refer to Alexander Joseph Grant. These report dates that more or less match yours, born May 10, 1863, Dufftown, Scotland, died 1955, Montreal. One of the two entries also includes some data about a wife Maud, but reports her name as Maud NASH, born Oct. 14, 1877, Holloway, Middlesex, England, died Dec. 16, 1964, Toronto. It's possible Nash wasn't her maiden name, but a prior married name. It's also possible those details are in error, but I have no way of verifying any of it--I don't have access to Ancestry International, so can't search Canadian censuses or anything else.
Again, I can't find a thing in Indiana to connect to any of these people. Sorry!
