Hello again Coils. yes, I know Clarendon Park a little, I worked at Hind's Chemist on Queens Rd. many tears ago! I knew of the BritisH Shoe, a friend of mine worked there, a carpenter/cabinet maker named Tony Snow, did you know him? He made the table for the boardroom.
I've been re-reading this thread, trying to sort it out. The reference to Thomas Meadow's children is not right, could they be William's children, I wonder? Thomas' children were: Asenath, William Jenkins, Mary Louise, Emma Keturah, Henrietta Balson, Arthur Balson, Thomas Edward, John Pretious, and Selena Elizabeth. Do these names ring a bell with anyone?
The obituary for William, son of Thomas Gillam Esq. sounds right. They were yeoman farmers, with an earlier Thomas being given the title of 'Mr.' in the registers, and 'Gentleman' in his Will. They are buried within Countesthorpe Church. Jonathan Gillam, who inherited the manor house, was the last of this line, he had one daughter who died young. I think they had sold off most of their land - which seems to have been most of Countesthorpe! - including the mill, when things became tricky for farming in the 19th century, as he is shown as a market gardener and seedsman.
I have some photos of the house, including one of the rafters carbon-dated to about 1496, but no idea which section I can put them on. two are on Genes Reunited if anyone's a member there.
