I am in Cole Harbour, Nova Scotia and no exactly where Carroll's Corner and Gay's River are located. I have been researching the Carroll's as my daughter in-law is a Carroll that goes back to Patrick's son Mathew and Terrance's brother. It was mentioned in earlier posts that Gay's River is not on the map. Well now a days it is so Goggle both places and you will find them. There is also a community website for Carroll's Corner. Make sure you include Nova Scotia in the search name.
Also John's and Alice's grave maker is located in the grave yard of the Gay's River united church - see my picture.
In the future I will be researching the land grants and sales in these areas to determine the locations of the Carroll's though the times. There is also an Eddie Carroll who owns his pareants farm in CArroll's Corner he goes back to Terrance Carroll. I don't know who but someone was in contact with him a few years ago and gave him his lines going back.
I hope this gets through! please contact.
