Morning Liz,

most important look up to do at Museum is the Baptism of,

JOHN CAIN Christening: 30 MAY 1859 Braddan, Isle Of Man, Mother: JANE CAIN

check in the Parish Register
and
also Check in the Bishops Transcripts

(this is a copy of the Parish Register done for the Bishop, and sometimes there are extra notes added to it by the minister)

ask the Librarian if there are Bishops Transcripts for BRADDAN in 1859

Good Luck !
Averil
