Hi,
Remembering the rounding down of ages, this looks possible for the family in 1841,
1841 HO107/625/7 f.40 p.28 St George, Lincolnshire
Borough of Stamford
Gas Lane
Elizabeth RIDYARD 50
Robert " 20 Silk ph?? Weaver
Mary " 15
Elizabeth " 15
Thomas RIDYARD 15
Richard " 15
Stamford is only about 23 miles from Kettering, Northamptonshire, where Richard later married and lived.
Regards
Daisy
