|Name of child||Date of birth||Date of baptism||Parish of baptism||Possible namegiver|
|Elizabeth Mary||16 Feb 1753||22 Feb 1753||St Martins in the Field||The middle name of Mary is probably after her mother, but I'm not sure who the Elizabeth honours. I haven't found an Elizabeth amongst the Baumgarten or Joynes relatives so maybe she was a family friend. It's possible that it was for family friend Elizabeth Worrall - see Lucinda Worrall Baumgarten below.|
|Marie||21 Jul 1755||15 Aug 1755||St Margaret Westminster||Probably named after her mother.|
|Charlotte||24 Feb 1757||28 Mar 1757||St Margaret Westminster||Probably named after her maternal aunt or maternal step-cousin - her maternal uncle Samuel Joynes was married to Charlotte Tully, who had been widowed by the death of her first husband Stephen Downes. Charlotte and Stephen had at least three children, including a daughter, Charlotte, and a son, Tully.|
|Tully||c1759||19 Dec 1759||St Andrew Holborn||Probably named after his step-cousin Tully Downes.|
|Thomas||c1761||7 Feb 1761||St Andrew Holborn||Probably named after his maternal uncle Thomas Joynes.|
|Henry||c1761||7 Feb 1761||St Andrew Holborn||Probably named after his maternal uncle Henry Joynes.|
|Frederick||c1762||20 May 1762||St Andrew Holborn||Either named after his paternal uncle, Frederick Baumgarten, or after his father's second middle name.|
|William||c1764||2 May 1764||St Andrew Holborn||I've no idea who William was named after!|
|Frances||c1765||2 Jun 1765||St Andrew Holborn||Probably named after her paternal aunt, Frances Baumgarten.|
|Lucinda Worrall||30 Sep 1766||16 Oct 1766||St Andrew Holborn||Lucinda Worrall's middle name was in honour of Elizabeth Worrall, spinster of Kensington, who was her godmother (noted in Elizabeth Worrall's will). The reason for the choice of Lucinda as her first name is unknown.|
|Joynes Philip||c1768||7 Dec 1768||St Martin in the Fields||"Joynes" is clearly derived from his mother's maiden name, no idea where "Philip" comes from!|
It was a very helpful exercise to put all this information into a table - firstly, I had an idea that Thomas and Henry were possibly twins, but realising that they were both baptised on the same day, when none of their other siblings were baptised with another, makes it more probable that they were twins. I wonder if they were identical or fraternal (fraternal being hereditary).
Secondly, I originally had a problem with Lucinda Worrall Baumgarten - I had her birth year down as 1756, and yet she was baptised 10 years afterwards, unlike any of her siblings. Plus, based on that birthdate, when she died in 1859, she would have been 102 - which I felt was highly unlikely in that day. Add to that the fact that she was baptised at St Andrews Holborn, when the two siblings apparently on either side of her - Marie and Charlotte - were both baptised at St Margaret Westminster. However, if we assume that 1756 was a transcription/typing error, and in fact she was born in 1766, that all works much better.
