Which Mary?

[AlisonKelly1958]

I was wondering if anyone can help me again?

I am still looking at my father's side but his maternal line
I have his GG grandfather as Richard Wright- born abt 1823- he marries a Mary in 1843 (Lapish or Bamford) who shows on 1851 & 1861 as being born in Leeds born abt 1821, then as Mary A born abt 1826/8 Royston Herts in 1871, 1881 & 1891

I can't confirm either or both Mary if the 1st one died, left him etc
Any suggestions- I find marriage documents/searches really difficult to fathom

Many thanks

Alison
