If you check the 1881 census you have Hiram Grigware in Springfield MA and several additional children,Ellen,Henry,David,Sophia, Philoma,Hiram and Joseph. Julie Anne could have been married by then as Ellen is 21. I suspect Hiram is Abraham Gregoire and the census shows Philomia as his wife,which is probably Philomen, a popular name in those days as was Louisa. If I find more I'll let you know.CarolG
