These four brothers plus sister Mary Caroline Briggs (my g grandmother) were b. in St John Co NB abt 1840-1851 to Joseph M Briggs and Esther McKee. Joseph M was said to been a sea Capt and born in England. Evidently he died some where as Esther remarried 1854. Mary C emigrated to Boston MA abt 1873. Looking for descendants of the four brothers hoping to trace their father.
