Meyers

I need the identity of the brothers Meyers mentioned in Zion's Watch Tower. The Meyer mentioned in the 1886 Tower is probably G. M. Meyer, an age to come believer. There is another who was an early days evangelist. Russell spells his name "Myer." He may have been Fredrick W. Meyer, but at this point that's just a guess based on ephemeral information found in an 1891 newspaper. This is rather urgent.

Can you help?
