1911 help please

[brummy]

Hi

I have this family in 1911, with James and Harriet (nee Innes) being a married couple

RG14PN17581 RG78PN1076 RD375 SD1 ED6 SN78
Frederick Adams  Head, Single, b abt 1846 Brimfield, Herefordshire
James Maund, Brother-in-Law, 22 years, b abt 1845, Wyson, Brimfield
Harriet Maund, Sister-in-Law, b abt 1861 Commonton, Ludlow

A couple of questions
1: Could anyone tell me if there is an address for this entry
2: What would the "22 years" denote on James Maund's entry
3: Can you have both a Brother and Sister in Law that are a married couple!!

Any help would be greatly appreciated
