I found Esther in 1851 and her youngest child was John b abt 1837. This is presumably his birth reg:
HALE, JOHN mmn ESTHER CHAMBERLANE
GRO Reference: 1837 S Quarter in ORMSKIRK Volume 21 Page 371
So, mother's whole name rather than maiden name!!
What is your source for Esther's maiden name? Presumably not just that you "thought it"!!!
