You have an unsourced profile that currently has no dates and no geographic information. Before you change the profile you need to document the sourced information you have about this family. Put the information and sources in the text section of the profiles. The profile for his son cites a probate record, but the son's profile doesn't indicate what you learned from that probate record. Is there a will or distribution that identifies wife and children, or possibly siblings and even parents? Is there a marriage record for the son? Those sometimes name the parents. Is the son (or this man) listed as a head of household in U.S. census records from 1790 to 1730? Document what you know and build from there...
