Just looked at some trees on Ancestry for Mary Ann Pick* born around 1851 at Hill Top, Staffs, as from 1901 census.
She is in 40 odd trees on Ancestry, and a few have her Mother as Ann Wilcox, around 1825 to 1890.
Have not looked further.
OK, quick look, think Dinah is a servant in 1841, and can be found in other censuses, this looks like a possible birth:
Dinah Wilcox baptised 8th April 1822 at St. Matthews Walsall, parents John and Sarah
Seems to be an Ann Wilcox (proposed mother of Mary Ann Pick*) baptised at same time.
