Hi,
I don't know of a link to those you mention but I have been looking for information on McAdam(s) in NE Ohio over the years. My G-grandfather Owen McAdam resided on the West bank of the Cuyahoga in Cleveland about 1876 until he passed away in 1888. He married Mary McCue there soon around 1876. We think he came from Co. Monaghan in Ireland around 1875 and was born around 1854 to Edward McAdam and Susan Lenan. We're not sure how he got there but we have thought about the ships and sailors. Cleveland City Dir showed a James living on West bank at times during those years and also Andrew, a ship's captain, perhaps related to those you mention in your email. I'd be interested in any information about McAdam(s) in NE Ohio. I still live in the area.
Thanks,
Tim McAdams
