Dave and Nick,
What a fantastic job you have done Dave. I really appreciate it all. I am now able (when I get the time) to extend the Phillips_Constantine tree further. You seem in a few days been able to move this on.
It took me months of odd moments to get not very far in the pre computer indexed days as you probably know. As to Thomas's father as Benjamin, I have long suspected that. The Directories show Thomas having a Tailor's business in Kington in 1844 but in 1835, the directory shows the same in Market Place as run by Benjamin Phillips. With the name and trade I was beginning to wonder whether we were looking at a Jewish ancestor with different records. There are many Jewish Tailors and a Master Tailor in Savile Row could be a good indication..
Also, yes there was a tradition in the family to use a mother's maiden name for the baby's middle name. My father was Rowland Constantine Phillips. Yes I too am a descendant. Family tradition says that one of the Thomas' was known as Thomas Tringham Phillips. I have never found any links for this. But there is also a tradition that Thomas' first wife died of TB. Nic, you will have to sort out the generation it might be.
Not only did I spend 6 months pursuing Phillips/Watkins but also Phillips/Joseph as marriages - both wrong as it now turns out. With computer indexing these can so soon be discarded. I have a copy of the Phillips/Watkins Marriage Certificate from which I was able to confirm this was wrong.
