The list I have is a list of birthdates for Tolbert & Rose and their siblings.I also have a picture of Tolbert, Rose and their children.Here is what I have:
Tolbert Weibel, Oct. 6, 1872 Rosa, July 5, 1882 Ralph (my deceased husband Neil's father), June 1, 1903 Wheatland Knox Co., IN Ruth, March 9, 1905, Wheatland Knox Co. Beulah, April 30, 1907, Wheatland Knox Co. Howard, January 5, 1909, Montgomery Davis Co.(Is this your father, he is just listed as Howard?) Arnold, July 28, 1911 (I think, the ink is smeared a little)Montgomery Davis Harley, January 30, 1917, Wheatland Knox Co.
There is another brother listed on Ralphs obituary, his name is Charles and at the time (1973) lived in Bicknell.
I don't know if this is information you already have, but if not I hope it helps.
