Thanks for all of your efforts here. Does seem to be quite a complex family to trace. I knew of the Binsted Hotston line and have had many pints and country wines in that pub over the years.
Interestingly there is a recorded marriage for a William Hotston from Binsted to a Rhoda Roberts from Bury in 1806. Unfortunately this conflicts with other sources as mentioned below.
The IGI contains a good amount of local Hotston records but most of these are not based on Parish records, they seem to be based on data from an LDS member e.g the birth of Rhoda in 1819. I am having major trouble trusting this stuff. In many cases there seems to be a birth date recorded but no christening date. I do find this strange, perhaps the LDS member had access to a family bible. I have put together the following Hotston family including Rhoda, from various sources including the IGI and just by using Google. I may try and get access to a fuller version of the parish records for Ford if they exist, the version that I have is from the SFHG but is a very old transcription with restricted dates.
