It is somewhat unclear as to what you are looking, and in what time period. (Lack of any punctuation at all just jumbles it all together.)
I think you are looking for the parents of Sarah Devlin, and that you have found her birth. What date and where was that? (that information is needed in trying to find them).
How is Sarah related to 'Hugh and Margaret'? Is Hugh's surname Mcorry, as you have quoted in brackets after Margaret's name), or was this her maiden name?
It could be either, as you have previously put the maiden name of Peter's wife Jane in brackets after her name - at least that's presuming the 'm' in the brackets means 'maiden name'.
It pays to be quite specific about what information you have, and what it is you want to find out, for anyone to try and help you.
Start with the date and birth place of Sarah Devlin, if that's the last piece of information you have.
