Quick update and odd query for your comment and thoughts please.
Now have collated a spreadsheet of hell of all possible James/John/Joseph/Josiah Davidsons/Davisons/Davies/Davies that I can trace coming to and in OZ between 1810 (age 10, young crim) and 1835 (when first daughter is born) and am slowly attacking each one. I have traced all the Minstrel possibilities (including the captured bushranger using the alias Davidson - he is also known as Wilson & Writson so this could possibly explain some confusion). Minstrel suspects are nearly eliminated. Coromandel suspects (James Snr, James Jnr & John) are elimi" nated (Am 95% certain that James the younger is the one who married Eliza M Sutter, probably the one who got "done" a few times for alleged "cattle stealing" (although whether he actually did steal them is somewhat debatable) and is therefore possibly got the Col P. Plus some others so only have 76 listings of possibilities left to go. But have had a lovely time trawling Scottish court records in order to eliminate some suspects (or not) as well as going through all your helpful weblinks.
The suspect who is currently piquing my interest is a John Davidson who arrived on the Baring 2 in 1819, convicted in Aberdeen - but have not found his court record(s) yet, which is frustrating as all the other Scottish suspects/court records have been easy to find. I keep trawling!
However, when the above exploration was driving me mad I went through (with a fine tooth comb) all the documents collated on the daughters of James Davidson.
Daughter Jessie Davidson's baptism certificate of 1835 (St Philips parish Anglican, minister the famous William Cowper) was a little "sparse" with information so I contacted the relevent Anglican Church and (I love them) they photographed the baptism entry from the register and sent it to me via email. No additional info on in except is the most beautiful handwriting.
I only have a jpeg of the second daughter's baptism certificate - Mary Jane Davidson in 1838 - which was emailed to me by her descendant. But is is somewhat intriguing and has got me thinking ...... Mary Jane was baptised 5 months after birth at Parish of St Andrews by the interesting Rev J Garvie Presbyterian (somewhat delayed) AND Parents ABODE is listed as:
"Sydney now Port Phillip (Geelong)"
This is odd ..... what do you think this means?
I have sent off a couple of emails to the Presbyterian people to see where the actual register would be held (I believe Rev Garvie's church is no longer) but have not heard back yet.
