Mark, I know that there was a William Molsbee in Saline County, IL on the 1850 Census and he shows his age to be around 55. He shows he was born in Tenn. Our Nancy Molsbee was married to a Maryland Mallady and they settled in Saline County after 1850 as they are in Livingston Co., KY on the 1850 Census and on the Saline Co., IL Census in 1860. She died in 1864 and Maryland remarried and died in 1875. I don't think this William is a father to yours, but could be a brother. Please let me know if you have any info on these people. Appreciate any help.
