I wondered if this passage (Aeneid IV ll. 663-666) inspired the name Taliaferro - my Latin prof thought it didn’t.
dixerat, atque illam media inter talia ferro
conlapsam aspiciunt comites, ensemque cruore

The Italian name is usually spelled Tagliaferro and the English with surname Taliaferro are said to be descendants of a man from Bergamo, Italy. George Wythe's wife was a Taliaferro and Thomas Jefferson did some research on the family during a trip to Italy. It is sometimes spelled Tolliver which is how the name is pronounced (at least in the US). I doubt there is any connection with Aeneid IV.663.
