I'm a bit confused now. If you can find the Ford burial record you want on Ancestry, there are usually two entries. One records the date of burial and the grave number, often with a number of other names following recorded as buried in the same grave, in the case of a public grave. I have always assumed this was the grave diggers' own record. Sometimes it has notes about a private grave and a burial planned for a particular day, mentioning flowers. The second record seems more 'official' and usually has the address where the deceased was living, in addition to the grave number.
There is no way of searching by grave number on Ancestry. I think there may be a privacy issue tied up with this as I gather the Ford records included the name and address of the person who held the grave deeds in the case of a private grave. As there may have been much later burials in a grave first purchased by a family in 1900 say, with the grave deeds being passed on to the next generation, names and addresses dating from a much later period may appear in them.
