I can give you all of the info you need on the James L Bean that died in 1885 but are you sure you have the right guy? This James was born in 1810 and seems a bit old for the Civil War. Now my Great Great Uncle James L Bean was born in 1836 and his gravestone shows that he served in "Co E 23 Wis". He is a brother to my Great Grandfather and the whole family lived in Wisconsin in the mid 1800s. James L. Bean of 1836 died in Latah County, Idaho in 1909 and I have a picture of his gravestone if you would like to see it. I also have all of his family information.
I would have to know which William Bean you are looking for because there were several in the Bean family in Wisconsin. Any other clues?
