Good project choice! I'm finding it harder to trace the Reids than the Smiths, and would welcome the opportunity to collaborate.
I'm researching two Read/Reid lines. Eliphalet Read migrated from Rehoboth, Massachusetts to a part of Nova Scotia Colony that's now in New Brunswick, among the New England Planters in the 1760's.
The second, William Reid has been a bit of a brick wall - there are simply too many William Reid's! A distant relative suggests his ancestor Alexander Reid emigrated from Scotland to Nova Scotia in the 1780s, but so far I haven't found any sources to confirm or deny the suggestion, or much clear information on Alexander.
I'm hoping to make a trip to the east coast to look in the paper archives, there may be information that's not yet online. I'll tag my Reid/Read/Reeds for the study shortly, and share any sources I find as I make progress.
