The dates and locations of your Stephen Pickle are just too close to my line not to be related!
I have Eliza Pickle, born November 16, 1832, Ontario, Canada. She married William Nolan, also born in Ontario. Their son Frank Nolan was born about 1857, Scogog Island, Ontario.
About 1858, they moved to somewhere in Michigan. William enlistd in the 3rd Michigan Cavalry in 1862, his residence listed as Kalamazoo. The 1870 Census shows them living in New River, Huron County, Michigan. I have not yet found them in the 1860 Census.
Eliza's death record lists her parents as being Niles Pickel and Mary Scoffield, although perhaps Scoffield is actually Scovel???
Eliza and William's daughter Lena Isabel Nolan McDonald was my Great-Grandmother.
