From the experts:
We've seen babies with Texas city names like Austin, Houston and Dallas--, why not the unexplored Laredo, which has a lot of cowboy charisma? Laredo might make for a more modern and creative namesake for an Uncle Lawrence/Larry--as could the related Laramie.
There was a 1960s TV Western series about the Texas Rangers titled "Laredo." There is also a famous cowboy ballad, "Streets of Laredo," recorded by Johnny Cash, and a Band of Horses song called simply "Laredo."
