Hi
It's definitely Johnathan he was buried at Caldbeck 15.11.1780 or 2 Sep 1808.
There is a earlier Johnathan buried 15.2.1756
Other burials who are not children 1716-1796 - Jane 5.11.1768,John 9.10.1763,and John 30.1.1774.
Also Joseph s of Johnathan and Mary buried 27.3.1780.It seems Mary didn't die until 8.4.1822.
It does look to me that the earlier baptisms before c 1750 may not be on line,have you checked them manually?It looks like there was an earlier generation in the parish.
Benjamin and Mary,Joseph and Mary and John and Susan nee Bell married 2.4.1758 also seem the same generation as Johnathan.
I'd be surprised if all the brothers suddenly appeared in the parish without their parents.
