Sansfamily on Family Tree Circles

I'm looking for descendants of Firmin Cackestor(Freeman Castor) who was born in E. Canada abt. 1788. He was living in Highgate,Vermont in 1860.His wife's name was either Mary Louise also from Canada.
Their son Freeman(Firmin) was living in Sheldon,Vermont in 1860.
The family name later on changed to Curtis.
I believe there is also another son named Louis Firmin Cassista Dit Castor who was born 9 July 1834 in Qu?bec and died 23 July 1903 in Keene,New Hampshire.
I would like to locate others searching this family.
Thank you.

My great great grandmother was Philomene Curtis, also known as Felina.
She was born abt. 1846 to 1852 in Brandon, Vermont. She died in 1931 in Worcester, MA. Her parents names are listed as Freeman Curtis and Marie Ann Proulx. Her death record states both parents were born in Canada.
I'm trying to find out if the Freeman Curtis who is listed in the 1881 Stanstead census was married once before he married Amelia.


There is a native american connection to this family, which I believe is from the Proulx side.

I would also like to know when and where Freeman Curtis died.

I don't have any other information to trace this family.

I hope someone can help to find more information about Freeman and where was he living around 1850.

Thank you.
