I like this explanation pretty well. Also, the state motto of Texas is "Friendship",
based on the Caddo word.
 
Philadelphia seems a longer shot- its name most commonly translated as "brotherly 
love" but as the center of the "Quaker" religion the preferred name of which is "The
Religious Society of Friends". 
 
Moreover, Texas is more like a "Land" while Philly is more like an urban jungle.
