On the BCC site we have a William Byng 1835 listed as the son of Josiah, I think he is actually the son of Thomas Byng 1802 & Elizabeth Hodgekiss 1806-1880 marriage Alvechurch Oct 30 1825 (not yet on BCC site) Josiah did have a son William but he was born in 1842 baptised at St Johns Bromsgrove Sept 25 1842. my research was carried out at Worcester archives, I've since checked IGI listings which seem to confirm my findings.
