She is not listed as a daughter so it is likely she is an adult and married to a Coate. Sadly everyone else who was buried that year in Curry Rivel had a relationship stated. That might indicate that her husband had died many years before. There are many Coate males in the area whose wives we don't know the names of.
Joane married COATE  [MRIN: 6176] before 1751. (COATE  was born before 1731 of Curry Rivel Parish, Somerset, England.)
