My grandmother's grandfather was also James Harvey so we are closly related. I will send what I have on the decendents of James Harvey when I get home tonight, I don't have the data here at work.
LB (my grandmother's father) was one of James Harvey's three sones that only had initials , AI,RD and LB. LB was a mailman in Waukegan and was killed while working when he was hit by a Northshore train (about 1922) at Glenflora ave. The railroad settled by giving his widow some property at that crossing in Waukegan and LB's son had a garden store there for many years. My grandmother married John Brink and moved to chicago about 1915 and lived on the north side and in Evanston.
I have some photo's of LB and one of James Harvey, plus some others from around 1910 of Miltimores in Waukegan.
Good to here from you, I will try and send digital copies of the photo's tonight or this weekend.
