I have John and William as two of five children of James and Sarah Piddle/Peddle. John was baptized in 1841 in St Paul's Anglican Church Index and William baptized 25 June 1843 in the same Index.
Please feel free to correct any errors I may have as my data has been gathered from many sources, but here is some additional info on these two individuals.
John married twice.... first to (Mari)anne Helyer Locke, daughter of Mary Helyer/Hilyard and Aaron Locke. Marianne was baptized on 15 June 1845 and married John Peddle in 1862. John's second marriage was to Isabella Janes, daughter of Mary Ann Weldon and William James. Isabella was baptized on 20 Aug 1836. They married on 23 Nov 1871.
William Peddle married Maria Waldron, widow of John Ryall. Maria, daughter of Jane Spurrell and Joseph Waldron, was baptized on 9 Oct 1847. They married on 6 Dec 1873, William listed as son of the late James Piddle.
Hope this helps! Please let me know if any of your information differs from what I have.
