Sillars from Arran by way of Canada

My great-great-grandfather, whose name I don't know, left Scotland during the 19th Century and settled on the Gaspe Peninsula of Quebec. There is still a tiny town called Sillarsville, QC where some distant cousins live.

My great-grandfather, Rev. Angus Gordon Sillars, left Canada and settled in Minnesota where I believe my Grandfather, Rev. James Rodger Sillars, was born.

My grandfather came to live in Massillon, OH, where my uncle, Rev. Rodger Battelle Sillars, and my father, Donald Graham Sillars, were born. My father was born in 1930.

I was born in Bethesda, MD in 1956.

Because of the steady migration of my branch of the family I have no real knowledge of the collateral branches, but no doubt I have reasonably close Sillars cousins in Canada, New England, and the Midwest.
