Hi Lee,
That's an interesting story about the Youngblood name. My research in Morgan County has involved Youngbloods as a collateral line of my Henrys. I have a different origin of this family. My Henry line begins with Nicholas Heinrich who was in Lancaster County PA in the late 1700s. He had a sister who married Daniel Jungblut in Lebanon Twp. PA. These two families moved together to York County and after the Rev. War Nicholas Henry and probably Andrew Youngblood moved to Morgan County. I believe that Daniel Jungblut (b. ca 1742) (Youngblood) stayed in York County PA and died there and the Andrew who is in Morgan County in the 1810 census may be his son. (This is speculation.) Andrew probably had sons Samuel and Daniel who were the ancestors of most of the Morgan County Youngbloods. By 1820 Andrew is dead and Samuel and Daniel are living next to each other. Daniel eventually moved to Ohio but I believe Samuel stayed in Morgan. I haven't been into this research in years so much of this is from memory. Your Reese , I believe, was a son of Samuel Youngblood as he is named in his will of 1846. I'll be gone for several weeks but if you want to know about my conclusions, I'd be happy to get back with you.
