Hi naffigirl,
Maybe this will help to find Artichoke yard?
Enumeraters walk 1871
15 Vine St
4 & 5 Houghton's Yard
Swinegate-Artichoke inn
11 Swinegate
1 to 8 Artichoke yard
1 to 4 Marshall's yard
12 to 21 Swinegate
1 Chapel St
Wonder if Artichoke yard was cottages built back of/adjoining Artichoke Inn

Just a guess??
1891-William (witness?) shows up!
46 Boden St Old Radford Nottingham
Henry Asa Walker head 55 Fitter Nottingham
Elizabeth wife 55 Grantham
Rachel daughter 25 Milliner Grantham
Ellen Eliza 22 Hosiery hand Grantham
William Thos(?) son 27 Engine Driver Grantham
RG13 2685 100 29
possibly William was with grandparents in 1871??
1901
46 Boden St
Olsd radford Nottingham
Henry A Walker head 65 Nottingham
Elizabeth wife 65 Grantham
Ellen E daughter 37 Hosiery Cutter Out Grantham
Florence? R? Grice Granddaughter 7 Wolverhampton

Rachel Holmes daughter 3 Milliner own a/c at home Grantham
Mary E Williams Neice M 37 Brass bobbin winder lace Grantham
RG13 3181 99 10
ages (and some names) are a little vague, as census entries must have been made using a poker!!!!!!
Possible death for Henry
FreeBMD
Henry A Walker
Dec qtr 1913
Nottingham
age 78
7b 401
I can't successfully locate Henry in 1861 (or his marriage to Elizabeth)
Wondered if he had been married previously?
There is a marriage Basford dist 1861 of Henry Asa Walker -but not enough brides to tell who he married

? Maybe it is his marriage to Elizabeth???
Hope this helps
Suz
