John,
I think you're probably right. Good thinking, searching on the mother's maiden name.
This is a list of Springs born at Ridgmont according to a parent search on IGI:
Father: JOHN SPRING Mother: MARY [surname shown as COX in one record]
JUDITH SPRING chr.26 APR 1801 d.25 JAN 1804
MARIA SPRING chr.24 FEB 1805
WILLIAM SPRING chr.29 MAY 1809
SAMUEL SPRING chr.22 APR 1810
MARY ANN SPRING b.10 JAN 1812 chr.29 MAR 1812
JOHN SPRING chr.04 FEB 1816
There may be others, but there is also another Spring family a generation back with the same parent names.
My only reservation is that I couldn't find any further reference to a William Cant/Kant in subsequent records, but we all know that people can disappear without trace . . . in my own family, there is a 40 year gap in one man's life until he suddenly re-appears in 1891 as a widower, and I have no idea where he may have been in the interim.
Mike.
