I too live in Minnesota (Shorewood) and I'am a descendant of Ralph Keeler. Do you know when your wife's branch of the Keeler family came to Minnesota and where they originally settled? I've done some research on the Keelers in MN but don't have much info. Would her family be connected to the Keelers that settled in Buffalo?
If you are interested, I have a copy of a daguerreotype of my 4th g grandfather Jeremiah Keeler, 3rd g grandson of Ralph. Jeremiah was born in CT in 1760, was a revolutionary war soldier and died in South Salem, NY in 1853.
Thanks for your help Michael. Please feel free to contact me at our email firstname.lastname@example.org
