How to differentiate records for three different children in same family which repeated use of the same surname after the previous children died.

Do you mean --- as an example --- child # 1 John Jones died then child # 2, born later, was also named John Jones who died and later child # 3 got the same name John Jones?

I have many instances like this in ancestor families in the 1700's and 1800's. I have not felt any need to differentiate as their birth and death dates easily explain the situation.
