Hello,
My great grandmother was Isabella Tigwell but I am afraid I do not know of any children born after those that appear on the 1901 census, but have sent you a personal message re my connection.
My GGF was Richard Lay and I do not know very much about the Lay side, nearly all my information relates to the Tigwell line. I know Richard was born 1856 at Blewbury, Berks, and his parents were William and Ann, but I have yet to order a birth certificate to confirm this. I would, however, be very interested to hear from anyone with a link to Richard Lay.
