HIERONYMUS, illegitimate son of Charles "Martel" & his mistress --- (-after [782]). Herimannus names "Hieronimo Pipini fratre"[160]. 754, 775. Abbé de Saint-Quentin. The Vita Fulcuini names "matre Erkensinda, patre Hieronimo, quorum prior de gente Gothorum…alter {Karolo] regis avunculus" as parents of "Folcuinus"[161]. "Carolus…rex Francorum et Langobardorum" issued judgment in favour of Kloster Mettlach by charter dated to [782] which names "fidelibus…Erhardo, Walerano, Ernust, Warnario, Huncelinus, Warlando, Waltario, Rimigaudo, Hainrico, Gaeroni et Hieronimo comitibus…et Walachario seu comiti palatii nostri"[162].
m [ERCHESWINDA or ERMENTRUDIS], daughter of ---. The Vita Fulcuini names "matre Erkensinda, patre Hieronimo, quorum prior de gente Gothorum…alter [Karolo] regis avunculus" as parents of "Folcuinus"[163]. The cartulaire of Saint-Bertin names "Ermentrudis genetrix beati præsulis Folquini"[164]. Settipani supports the theory that Hieronymus married twice, Ermentrudis being his first wife and Ercheswinda his second, Audoen [I], Fulrad and Richarda being his children by his first wife while Folcuin [II] was his son by his second wife[165]. However, this appears to ignore the fact that both of the sources referred to above purport to name the mother of Folcuin. Unless new information comes to light, it appears preferable to assume that both sources refer to the same person. The Gothic (or Visigothic) ancestry of Ercheswinda, asserted by the Vita Fulcuini, has not been traced.
Hieronymus & his wife had [four] children
