Dear Meredith, I am also researching the LOOK family and am trying to connect these families who migrated to Michigan from that area of New York.The following appeared in a newspaper in the Batavia area.The name of the paper I believe is "THE DAILY NEWS" dated July 8, 1908.
Death of a Native of Batavia
"Mrs. Mary Look, widow of Asher Look and who was born in Batavia, died at her home in Otisville, Mich., where she had lived 35 years. She was 84 years old."
Otisville, Michigan in Genesee County is a county adjacent to Tuscola County where my great-great-great uncle James Look from Erie and Genesee County, New York located just after his service in the Civil War.The Tuscola County records indicate that nearly an entire town of people from the enviorns of Batavia moved there.I will research the Michigan records and let you know if I can find any connection between my family and yours.
