Great sleuthing Jen.

So back in the mid 1860s, and Queensland Australia
Samuel DROUGHTON was at Goondiwindi and Charles DROUGHTON was at Drayton …… and Julia DROUGHTON provided Goondiwindi as her usual address to the Rev OGG in 1876. She also said she was 27. So, if born 1835, and aged 27 when marrying, then the year would be about 1862 or 1863 …. Agh, from our OPs info re Elizabeth’s April 1863 birth cert, Julia and Gordon married at Ipswich in 1863…. See reply # 3 for info from Elizabeth’s bc, and passenger list British Empire for Julia being aged 24 in 1859 …. (Apologies , likely this link has been given earlier in this now long thread, but hopefully it is ok to duplicate it here for ease of other RChatters checking my deduced ages/dates etc

Please remember that the Qld BDM’s 1876 marriage registration is a transcription of a transcription of a parish register. Until the original parish register is checked we cannot be certain of the accuracy of that transcription of a transcription of that church record. Please also remember that when the clergy interview the couple, the groom supplies info about his origins and the bride supplies info about her origins. It is not usual for the groom to provide info about both his own parents and his in-laws.
And from that 1876 registration, Gordon said he was aged 29…. And from JW Blair’s info about Gordon on Gordon’s dc, Gordon was born Sept 1833. Sept 1833 plus 29 years …. Late 1862 to mid 1863 …. And the info that Gordon gave as informant on Elizabeth’s April 1863 birth …. He and Julia married at Ipswich in 1863.
Has anyone sought to contact St Pauls at Ipswich to see where their parish registers from that era are now in safe keeping …. Perhaps the Diocese Archives? As this is a C of E register, there could be a family sheet register too. It may have details about when Gordon and/or Julia became part of that church community….. (may even include exact dates, birth/baptism dates for their four children, etc).
