Welcome to RootsChat
I'm not sure which John TIMSON you are looking for as you don't mention his birthplace, if he is the one born in Rutland and married to Susan I think this could be him/them in 1891.
1891 RG12/3608 f.101 p.18 Wyke Yorkshire (Bradford Registration District)
13 Wyke Lane
John W Head 48 Mason Rutland Gt Casterton?
Susan Wife 47 Lincolnshire Langtoft
Clara Daur 22 Worsted Winder " Stamford
John W Son 21 Engine Cleaner? Railway " Stamford
Arthur E Son 15 Cotton ?? Yorkshire Wyke
Leonard Son 10 Scholar " "
I noticed that the John TIMSON in Boston Workhouse has an S for single in the marriage column and although these can be wrong especially if dittoed the rest of the inmates seem to have their marriage details as well.
