Hello, I'm trying to find maiden surnames by searching the GRO indexes for the births of the children - but keep coming across records that look right (name, date and place) but just have a dash instead of mother's maiden surname. Frustrating! Why is this - are some records just illegible / damaged? Might I be able to decipher a name if I got a copy of the record, given that I think I know what it might be? Are there any situations when the mother's maiden name would not be recorded? Grateful for any enlightenment, thanks!
