Sure, I mean most names come from old english, germanic, and french that are used in modern day English speaking countries, all the names originally were built through words, usually encompassing the jobs they did, or their parents did, or like for example Harrison, means the son of Harry, from old English. But most people nowadays have no clue the meanings they just use the name because they sound good.
I don't know what the names together mean, but looking them up separate I found the meanings. The meaning it gave for Tia is Aunt, which is what it is in Spanish. Lynn means near a lake or pond.
I'm not sure but I don't think all names necessarily have meanings, I think most are just chosen because they were names of relatives, or the parents thought the name sounded good.
Haha, well I guess Imma have to ask them 'cuz I dont know another Tia-Lynn in the family. Darnz now I gotta go find out who named me, hehe.
