One of my ancestors served for the Union in the Civil War with a Pennsylvania company. I found his pension
index record on Ancestry.com and also on other websites but this index card
does not tell me much.
Further searching using Google led me to the following website, though. http://www.angelfire.com/pa5/gettysburgpa/23rdpa.html
I’ve found similar websites for this regiment and another one is: http://www.pacivilwar.com/regiment/23rd.html
This website includes links to articles and photos.
Don’t just think it’s the Civil War that has websites for companies and regiments. My father served in WWII and there are websites for his Air Corps division, also. The best one includes pictures and transcribed strike journals! (I have my Dad’s strike journal and pictures but if I did not, this site would have been priceless)
The point is – we get tied up with looking for our ancestors information on generalized websites and don’t think about the possibility that the information might be on a special, dedicated, FREE website.
I’m sure there are sites for your ancestors who served, also.
