Francis Young also applied for a civil war pension. It looks like he served in Company K of the 1st Cavalry regiment of Vermont.
His application number was 209296 and his certificate number was 471866.
If you don't have his pension file, I would recommend that you get it. They are usually voluminous and have a variety of information since the government sent out an investigator to interview friends, family, etc. I have a number of them and my experience is that you never know what you will find in them.
You can order online at www.archives.gov/genealogy/military/
Let me know if you want any more info.
