Roy,
I don't believe the Margaret identified by Brian is the one you are seeking as her Killip ancestry is too far back to be used as a middle name. It is more likely that she was the Margaret Killip Moughtin born in Liverpool in the June quarter of 1877 to Manx parents Thomas Moughtin and Sarah Jane Killip who had been married at St Peter's in Liverpool in the December quarter of 1876.
Certificates for the birth and the marriage may be ordered on-line from the General Register Office
www.gro.gov.uk.
Margaret's father's name should be on her marriage certificate as well, also obtainable from the same source.
