As Frances suggested, the parish register might give the cause of the deaths.
This is an example from the Andreas parish register:
1832
“These 3 of one family (Balla-Correy) died of that awful disease with which it pleased God to visit the sins of mankind the malignant cholera. No more of this parish died of the disease at that time praised be His name. J Nelson Curate
John Radcliffe Aug 8th 59 years
Catharine Radcliffe Aug 8th 18 years
Eleanor Radcliffe Aug 10th 20 years”
