My Post office info only covers the years 1790-1833 and this just tells were the post office were. I found all the postmaster by a general search. The key word was postmaster and I had to look at each item to find the names. You are looking for men that were postmaster at Tulare Ca. and I need names to be able tell you if they were postmasters…LOL. If you have some name you think may have been postmasters sand them and I will take a look. If this search goes beyond 1875, I will not be of any help.
