not sure what the first letter is - maybe an 'O' ?
Are there any other letters on the cert that look similar that might be useful for comparison ?
After that there is a sequence that looks like it consists of 'r's 'm's or 'n's and possibly 'i's, followed by '..cughton'
does this relate to one of the people mentioned on the census links you have in the 1st post on this topic ?
