Foister is a rare and unique given name of English origin. It is derived from an Old French personal name, 'Fiustier,' which was itself drawn from the Germanic elements 'Voust' meaning 'upright' or 'proud,' and 'ari' meaning 'army.' The name Foister is believed to have been brought to England by the Normans during their conquest in the 11th century. Today, it is virtually unused as a first name, making it an unusual choice for those seeking a distinctive moniker.
"The name Foister was born to five children in 1924, making it quite uncommon that year."
