Casemiro Family Crest & Name History

Some records give Casimiro; others give Casemiro. Both point to the same Portuguese family name.

The family name meaning is “From Casimir”, the same as for Casimiro. Spelled with “e” instead of “i”, Casemiro shows how the same name was heard and written differently. Spellings drifted because names were written down by ear in parish books, tax rolls and passenger lists. Related forms: Casimir and Kasimir.
