Hello Leah, The convict Samuel POWELL - who was tried at Middlesex in 1819, received 7 years sentence, and arrived on the "Earl St Vincent" on 16 August 1820 - was aged 23 when sentenced, so would have only been 17 years old when he married Mary VAUGHAN in 1813 in Wales, a long way from London. Are you sure you have the right man? Do his convict records show if he was single or married? I could find nothing on the arrival of Mary VAUGHAN or Mary POWELL as a convict on the Earl St Vincent, which shows only 160 male convicts - if she had finished her sentence prior to coming to Australia in 1820 then she would have come 'free' accompanying her husband wouldn't she? Samuel POWELL was tried for stealing seven yards of cambric and tried at the Old Bailey. He received his Ticket of Leave (TL 489/1423) in 1820 (it must have been issued close to his time of arrival?), and was appointed a Constable at Parramatta in 1822. http://www.oldbaileyonline.org/browse.jsp?id=t18191201-96-punish556&div=t18191201-96#highlight If Mary was married in 1813 and convicted the same year, and she served 7 years before her arrival in NSW in 1820, was she tried as POWELL or VAUGHAN? And would a 17 year old boy have waited 7 years for her to serve her time, then immediately commit a crime himself and get transported? The story doesn't make much sense. Hope you can sort it out with the help of the Welsh lists Good luck, Trish Nowra NSW Who can help me I still have some hair left! My GG Grandmother Mary Vaughan who married Samuel Powell in Wales in 1813 in Brecon ( Breconshire Wales), no parents on the IGI, Mary was a convict and was sentenced to 7 years, information from my cousin Bernie who has been researching for thirty years so my time to pick up a thread, Mary finished her sentenced before she came to Australia in 1820 on the Convict Ship Earl St Vincent with Samuel, I have scanned the Old Bailey Records and found nothing, could she have been sentenced in Wales or maybe Scotland. Any input would be greatly appreciated. Regards Leah
