The first that I found was a marriage record for a Lewis Dorrity in 1840:
I don't have anyone named Lewis in my tree, so I had a look at later census records for a Lewis Dorrity (or variant spelling). I only found an individual in 1871, widower, who had an age that would have matched, but who was African in background. So, it would appear to not be a connection and I haven't found anything else to link the record to the rest of the Doritty family.
Next, I found this record in Ontario Marriage Notices:
The name uses a different spelling, of course, and there is no connection to the names or locations, so I'm going to rule out this one as a connection as well.
Next there were these two findings:
Francis Early Doritty is the son of Frederick Doritty and Laura Lamondie. While there is a Frederick Doritty in my tree, there is no connection to a James Doritty. And with the variant spellings, and different location, I'm prepared to say that this is not a connection to my family - or if it is, it is a distant connection.
