Sylvester in Arenac Co.

I am a direct descendent of Leonard J. Sylvester, born about 1824, originally from Macomb County and later lived in Lexington, Sanilac Co., Michigan. His parents were from Canada. He married Cynthia Melissa Torterlet.
She was born in MI, 1822 and died 1907 in Huron Co. MI. They had a son Clinton, married to Mary Laviolet. Mary's father
was Paul Laviolet fron Canada. Clinton and Mary had at least three daughters, Susan, Aldora, and Maud. I am looking for
descendents of these daughters. Aldora married Herbert Lincoln and they lived in Arenac Co.
