I am looking for information possibly regarding a disease outbreak in 1750. I have the children of John Black and Christian Prescott listed as follows:

John Black b.1740 d.1741
John Black b.1742 d.1750
Robert Black b.1745 d.1750
Elizabeth black b.1747 d1750
Thomas Black b.1750 d.1750
Robert Black b.1752
John Black b.1756

With four of the children passing away in 1750 I wondered if anyone knew if this was because of disease or maybe a house fire or some other accident. Apart from the first born the children were christened in Santon. Can anyone help?

Tom.
