Hi Robyn,
That link was fascinating - I looked around a little, however, and found a David Tatham (and his twin brother and the rest of the family including a sister who married into the Buchanan family) in the names index, so, ... no, doesn't look as if this is him. Good thought, though!
I might wander off to the Library and have a fresh look at what Ancestry has for the eastern States and Canada; - Laramie City, Wyoming, is a decent old hike from NY (where I assume he landed - haven't found any record of that yet, either!), ... so ... perhaps DJT still had "the bug", and crossed into Canada? Fingers crossed
