Hi Barbara You put me in touch with your Tidbury friend a couple of years ago now and I have all the details of her tree in my database. Her line goes back to an Elizabeth Tidbury b. c.1830 in Egham. Elizabeth was the daughter of William Tidbury, a labourer, but so far we've not been able to take the line back any further or connect it with the other Berkshire/Hampshire Tidburys. Best wishes Debbie
