As given in the Bigelow genealogy:
12959.1 Samuel, b __; d ___ Hartford; m unknown date, Abbie STEELE, who died about 1836; 3 children.
12959.2 Louisa-- it is the editor's suggestion that this may be a daughter of Samuel's cousin Jonathan by his first wife Louisa WEBSTER; see 12169.
12959.3 Mary, who proves to be a daughter of Jonathan and Ruth (STEELE) BIGELOW-12169; b 15 Sept 1799; d 13 Jan 1884.
12959.4 Ruth, who proves to be a daughter of Jonathan and Ruth (STEELE) BIGELOW-12169; b 29 Oct 1801; d 1882; unmarried.
Apparently Samuel took these last three children into his household when their parents died, and raised them as his daughters, but without formally adopting them. Editor suggests a careful look at probate and property records of this period. It may be that all 4 children were foster children, cf. Jonathan 12169. We must also not overlook the possibility that Samuel was a bachelor.
