I have been struggling for a while to find a birth for this woman. I have marriage, death, and on census' 1861, 71, 81, and 91 to her death in 1897. but cannot for the life of me find her birth.
she is: Ann Robinson, born depending on which census we read, either 1825, 6 or 7. born in, again depending on which census, Denstone Staffs, Sudley Derby, Stramshall Staffs, or even Uttoxeter.
she married William Mycock in1853 in stramshall or was it Uttoxeter.. and they lived in Stramshall, Kiddleswick and Uttoxeter .
can anyone help this muddle please?
