The name of this family is spelled a variety of ways. It is German and was originally "Wirth", pronounced "Veert". It is easy to see why the "h" was dropped the the "i" changed to an "e" by writers of English.
Anna Maria Rex usually appears as Mary Rex.
Peter is mentioned in documents concerning his father's estate.
It is interesting to note that four Wert sisters, Katherine, Susan, Elizabeth,
