Looking for information on my 2nd greatgrandmother Mary PROVO and her family:

Husband: Louis PROVO
Wife: Mary LATOUR
Child: Mary PROVO

Mary PROVO was b. 3 Aug 1860 in Plattsburgh, Clinton, NY.
She m. 14 Oct 1878 to William E. Blow in Grand Isle, Grand Isle, VT.
She d. 6 Nov 1953 in Huntington, VT
Rumor has it that there is an Indian connection...but no luck finding it so far. Any help would be appreciated.
