Thanks for responding. I am not aware of a connection between the PIKE family and any of the ones I am looking into (WILSON, CHESLEY, DRAPER primarily), but that doesn't mean there wasn't one. I am interested to see the connection to Orange Co., VT. That's where my WILSONs were before they went to Quebec. Hmmm.
I need to check to see if there were PIKEs around Moe's River in Quebec, where my WILSONs lived. They should be in the 1881 Canadian census. If not, they should be locatable in the index to the 1880 US census (or earlier indexed censuses.)
At any rate, thanks for pointing out the spelling "Adna" to me. I hadn't though to look for variants.
