Thanks Tricia for all that info, I did have some of it and it will take some time to get through the new info, (some very interesting websites there). And thanks for the offer of info on the Greswolds but unfortunately my problem is trying to find a link with John Williams of Pitmaston. I am hoping that my GGrandfather was a descendant of one of his brothers and as they were not as well known as John, I am finding it very difficult.
His brothers were:
Francis Williams(Magistrate)
Edward Williams (poss magistrate)
Henry Williams
James(?) Williams
& poss more
My family story goes something like 'he (my GGrandfather) was the youngest of 32 kids (no wonder there are so many Williamses!) and his father was a judge. John Williams of Pitmaston was a magistrate (as was his father). I tell you all this but I do not hold out much hope that much can be found. I have been trying to track down my grandfather - William Charles Williams for nearly three years now with little success to date.
But hey, its good to get it off your chest anyway and this is such a great website, so helpful.
So thanks

Sue
