Bill, in response to your question:
Our ancestors who came to Michigan from Scotland were John William
Sinclair and his wife Mary Graham, who were married January 1803. They
had a total of 11 children--8 girls and 3 boys. Two died in childhood.
Between 1804 and 1826, the family sailed to America.
The above is taken from a booklet from the Third John William and Mary
Graham Sinclair Family Reunion which Bill's and my sister, Margaret,
attended in 1984 in Northbrook, Illinois.
