N0 - 1861 Peter is with his uncle and aunt William and Catherine Bamber in Everton. He appears to live into adulthood. Parents on his baptism are Joseph, a porter, and Mary of Everton
Mary Ann Bamber baptised October 1846, daughter of Joseph Bamber (coachman) & Mary of Rathbone St.
In 1851 they appear to be lodging in Knight St with the Jones family. No Peter with them.
Mary Ann's birth registration suggest mother's maiden name is Pricket
Mother's maiden name for Peter's birth is Heaton. I also note Mary is 42 in 1851, so another child in 1857, whilst not impossible, seems a bit unlikely
Joseph and Mary are lodging in Rathbone St in 1841 with another son John b 1837
