Carole. Most of the information relating to Peter Walker has been verified apart from the actual date and location of birth and death, or his parentage. I was hoping to track down an official record of him being issued with the Smack Master's certificate.
The Liverpool parents Walker / Blackburn are guesses at best. His marriage to Florence Gertrude Swan and their children are all verified.
1911 welsh census has a Peter boarding in house as a deep sea fisher man.- status married. Given the discrepancy over his DOB from Marriage Record, Census returns and Prison record. There is nothing to confirm that this is 'our' Peter. Census indicates that Peter spoke English and Welsh - which gives some credence to him actually having been from Wales rather than Liverpool

Marriage certificate for his son Peter Robert Walker states that father (also Peter Robert Walker) was deceased. (1915) - however given the bigamous marriage he may well have been told that his father had died! It's the only reference I have that his father Peter may have had a middle name
Marriage record for his youngest son Richard Victor Hugh Walker in 1920 does not mention that his father Peter is deceased.
The 1921 Census of England, Wales, IOM, Channels Islands and Scotland have failed to unearth a Peter Walker of the correct age (+/- 5 years) who was a fisherman / sailor. It's probably safe to assume that Peter had died prior to 1921.
It puts the following records into question - and also whether it was actually 'Our' Peter who was in the 1911 census at Milford Haven
