Hi there

I am stuck on my 3x great grandmother her name was sarah wilkes born around 1819 in darlaston she married robert harper in 1838 who died 10 years later in a colliery explosion. She is living in west bromwich with my 2x great gran mary ann harper aged 12 and sarah is a widow. I can see a sarah harper on gro of marriages in the dec quarter of 1852 in west bromwich, there are 2 mens names given on the page number they are james duffield and Joseph Keay. I am thinking she married james duffield as her daughter mary ann married a john duffield in 1859.
Could someone please lookup this married for me, so its sarah harper she should be aged around 33 and a widow her maiden name should be wilkes. Many many thanks in advanced.
Also i may add i cannot find a james duffield and sarah in west bromwich of the ages they would be although there is death record a sarah duffield in q1 1872 in west bromwich aged 53 which would fit perfectly?
