Hi Sharon,
Although there are 2 on record from company B of the 7th Kentucky, there is no Anderson listed. I checked all companies of the 7th, and there are 23 on record as having been here but again, no Anderson. There are several John ANdersons on record from several Northeast states and 3 John W. but these 3 are from Ohio and Pennsylvania .

Do you have any documents showing he was here or suspect he was here?

Kevin
