Hello,
Ah, yes, they were buried in Tendring. I did wonder myself why they were buried together, clearly dying about the same time. It's possible in that period, with infectious diseases so much more of a killer than they are these days, that they both died of a fever, perhaps? Also, it was January when they were buried, so it could be that it was some horrible winter bug that did for them. Sometimes you see notes in the registers if a death is unusual - some poor soul in Moze (I think) died when the church bell fell on them! Then you get people in Greensted-juxta-Ongar dying in rather unpleasant agricultural accidents ("fell off a wagon, died instantly", "Impaled on his plough when his horse turned suddenly" etc), and in Acton in Suffolk, several children being "burnt to death" - these are later in the 1800s so I cross-referenced them with newspaper reports and one of my relatives died falling into the laundry copper when her mum nipped round to see the neighbour for a second.
Have you tried any other sources, like wills or the Poor Law stuff on the
ESfFH CD? Having a quick look on Seax - no-one with the surname Butcher writing a will in Tendring or Brightlingsea (of course, lots of people with other surnames, who worked as butchers!). The Poor Law cd is brilliant, if you're lucky enough to find an examination or such. One of my ancestors I'd traced to Great Bromley when he got married, but had no idea where he came from, and he died before the 1851 census. But luckily (or perhaps not for him) he was examined and it gave a full break down of where he was born (Mendlesham in Suffolk - wouldn't have known to look there otherwise) and all the different people he'd worked for, where and how much he earned. But of course, there's lots of other ancestors of mine who just don't exist in those papers, sadly.
