Thanks for replies.
scrolling thru common room archives [page 4] i found an interesting post by op snowball 05/01/16 on same subject, so see many answers there.
my post concerns an original imaged copy of a birth cert sent to me - it is a certificate - not a parish register entry and that was later used to verify the birth was recorded in the church from a cd produced by the church incumbent for his masters degree [social science 2005] where he transcribed the church records.
The event took place in Cheshire 1852.
the b.cert section for the mothers name is empty. the penciled entry is scrawled diagonally across the cert and I believe was written by my fathers hand since I recognise the scrawl. Since he is no longer able to rely to the query, I'm hoping the experts at Rootschat can drum up some suitable answers just to unravel one more oddity in the family past!
have at it please and thankyou kindly.
