Information on 19th Century Photographers near McKeesport Pennsylvania?

Question

I have a number of old photographs of family members on cards. I don't know who they are of, so I was hoping if I could determine more about the people that took the photos, I might be at least able to narrow down when they were taken. They are as follows:

1) Studio of W. H. Whitehead - McKeesport, Pennsylvania

2) J. R. Pearson - 96 Fifth Avenue, Pittsburgh Pa + 43 & 45 Federal St., Allegheny City, Pennsylvania (notes "Instantaneous Process Used Exclusively)

3) J. C. Moye - Amity Street, Homstead, Pennsylvania

I also have from from England:

Wilson & Co. - Bridgeton Cross, Glasgow

Any information on the photographers or ideas on making these photos less mysterious would be appreciated.
