I have found A Monumental Inscription in Braddan New Burial Ground (Douglas) Block 3
1 1549 Sacred memory of Ann daughter of Richard Cretney Ship’s carpenter of Douglas, Elizabeth his wife who departed this life 11 May 1851 age 6 months, also the above Richard Cretney who departed 14th August 1851 aged 33 years.
I'm sure this is Father of Catherine Jane C and younger sister Ann. No mention of mother's burial.
Could John Joseph C be mentioned in the bible as he is her brother?
There seems no record of family in 1861 census
