Frank M Clark Of Michigan

I am looking for my second great grandmother's family.
My grandmother was Myrtle L Clark b. 8/26/1874 in Antrim Co, Michigan. She had a brother Alexander who was born 1879 in Antrim Michigan.
Her father was Frank M Clark who was born in 1849 in New York where his parents were also born. (have no idea who is parents are or siblings). Her mother was Mary J Clark who was born in 1850 in Ohio.( I only know that Mary's mother was born in Pennsylvania, otherwise there is no more information on this family).

Myrtle married Daniel J MacClain (McClain) in February 1889. They had three children: Frank, Clarence, and Bertha.A few months after Bertha's birth Grandpa Daniel MacClain died in 1894. The children were placed in an orphanage and then were later sent to live with other families. I do not know if she ever got her children back.

Some time later she was remarried to Otto Lazinski. They had several more children: Otto JR, Franklin, Edith and possibly Helen. ( we cant yet verify this information).

Grandma Myrlte was known as "Little Grandma" beside she was also known as "Crazy Grandma" as family history states she suffered a mental illness.

Grandma Myrtle lived with her son in her later years. She died in October 1953 a few months after her son Frank died.
