My gg-grandmother was Mary Kent Bradbury who married Theodore Hart (of Montreal) in Boston in 1845. Mary's was born February 8, 1812 to Charles Bradbury and Eleonora Cumming.
The original Mary Kent Bradbury was born in 1801 to Charles's brother George and his wife Mary Kent.
Apparently, they also both had daughters called Caroline Keith Bradbury. Both of these grew up, got married and had families of their own.
These two brothers were sons of Theophilus Bradbury (1739) and Sarah 'Sally' Jones (1739), daughter of Ephraim Jones (1712)
