John,
Is your great, great grandfather James E Colmey of Chicago, IL?
If so, his brother was John Colmey, Canandaigua, NY, who was a prestigious lawyer and judge of that place. Their father was James, born Ireland abt 1817 and mother Catharine (nee Bishop), born NY abt 1831.
Hope this post reaches you and helps in your search.
