Your common ancestors with my husband are David C. and Lucinda (CAGWIN) Wilbur. They came to Michigan with their three sons in 1860, dying within weeks of each other in early 1880 at Custer, Mason Co., MI. I have a great deal on the Wilburs, but not so much on the Cagwins. (The surname is Cornish and was originally spelled KEIGHWIN.)
Job (sometimes spelled Jobe) Wilbur was David and Lucinda’s youngest child. He married Alma THOMAS 13 August, 1870 in Akron Twp., Tuscola Co., MI. Their children were Ambrosia Belle "Belle" Wilbur (1871-1829, married Charles Ewing "Charlie" LEMLEY, six children), Ella M. Wilbur (1872-?, nfi), Frank Alby Wilbur (1874-?), Mabel Wilbur (1880-1951, married James Ward HEISHMAN, no issue), Lucy Wilbur (born after 1880-nfi) and Myrtle Wilbur (1886-nfi). As far as I know, Belle was born in Lansing, Michigan; Ella and Frank were both born in Akron Twp., Tuscola Co., MI; Mabel was born in Eden Twp., Mason Co., MI; Lucy may have been born in Illinois and Myrtle was born in Arkansas. The Lemley descendants appear to be based primarily in Oklahoma and Texas. James and Mabel Heishman are both buried in the Golden Gate National Cemetery, San Bruno, San Mateo Co., CA. Myrtle appears with Job and Alma in the 1900 US Census for Harrison, Kootenai Co., ID. You are the very first of Frank's descendants to contact me. Sadly, the rest are still among the missing.
Job Wilbur purchased land in section 33 of Custer Township, Mason Co., MI in October of 1879 and moved his entire family there from Tuscola Co. shortly thereafter. He sold it two years later in October of 1881 at a loss and headed west. For the longest time, the only clue we really had to his ultimate destination was a Civil War Pension index card indicating that his final pension went to Idaho and anotehr that said Alma's widow's initial widow’s pension payment was sent there as well. I do not currently have Alma's death date or place of burial. Feel free to contact me privately for further information. Thanks to some egregious misuse of my material without permission, I have a policy of never transmitting detailed genealogical data electronically. However, I will be more than happy to send you a printout of what I’ve collected. My husband’s aunt, Janet Rumsey Wilbur, started me out on this project over 20 years ago and, like Topsy, it certainly has GROWN!
