Do you know the names of any daughters of Peter & Mary Ann (Crawford) Merry apart from Lizzie (Elizabeth) who is with them in 1911?
There's a marriage for an Elizabeth Merry to a William Brown 1933 Coatbridge
MERRY ELIZABETH / BROWN WILLIAM 1933 - 652/2 215 Coatbridge or Old Monkland
although the surname on the signature on the DC looks rather stretched to be Brown, however...
1940 VRs (Valuation Rolls) have a William Brown at 17 Arkleston Crescent, Paisley...
BROWN WILLIAM
Proprietor OccupierHOUSE AND GARDEN 17 ARKLESTON CRESCENT CARDONALD PAISLEY

I think Monica's suggestion is well worth looking at as the surname looks more like Bateman than Brown...
1947 marriage for an Annie Crawford and a William Robert Bateman in Hillhead?
Could Annie be a daughter of Mary Ann Crawford prior to her marriage to Peter Merry & possibly living with her sister & brother-in-law at the time of their mothers' death & her husband Wm Bateman registered the death?
Annie
