After a bit of research on this family, I find that the only on-line tree with proper sources has a scientific error of grave difficulty and thus has been added to my "Problems" file. Which brings it close to a dozen single spaced pages!
However, James is alleged in several unsourced trees to be a grandson of James W Abernethy & Lois Andres. I have doubts regarding that as well.
James is claimed to have been born b. 25 Oct 1822 in New York, USA, and died 27 Nov 1897 in Tuscola County, MI. His wife _may_ have been Canadian. However, a sourced on-line tree that claims these facts has errors in that two of James & Clarissa's children simply cannot have been born of the same mother if one was born in Jan and the other barely 7 months later. That was just NOT possible in the 1850's, which did not have the medical advances we today do! So I believe the research is either incomplete or flawed.
