Other sources list her birth on December 8, 1730. More research is definitely needed on this family and Esther in particular. Is she the same Esther Gleave, daughter of John Gleave who was born December 8, 1729 to a John Crozier (his birth date listed as 1703 in Ireland and death in 1786)? This is just too coincidental. A search of the Springfield, Chester County, Pennsylvania records is necessary to clear up the relationships. I believe that if documentation can be found and proven, that these "two Esther Gleeves/Gleave" are the same person and John Crozier that they married is the same man. More searching is needed.
