Some years ago I spent a full day at Bury St Edmunds library checking ALL the parish records (births and marriages) for Brandon, Suffolk, England. The only Robert Rampling of suitable date was baptised on 27th December 1829, the third child of Henry and Sarah. Henry's father was also called Henry and he was a son of Edward Rampling who you mentioned in your post.
If you want more detail email me! I have information of about fifty Ramplings in Brandon between 1750 and 1850.
