William Kendall - Land Tax of William Kendall....death date questions?

in 1742 William was taxed for 342 acres by 1768 a William was taxed for 196 acres and Joshua 142 acres.

In the old Stafford County Deed Index there is an entry that appears may be a divsion of land or deed gifts. This entry was during the 1760s.

Also the Overwharton parish records are from c1730-1758. We have to review what is included and excluded in the record. Most of the marriages and births of the Kendall children are listed. The fact that there are no deaths suggest. Neither William or his wife Elizabeth died during this time. We could theorize any deaths occurred before 1730 or after 1758.

The Stafford County, Virginia tax lists does not show a William Kendall during 1783-1790. Either he was not listed, levy free and living with children or he was already deceased by 1783. Based on this I question a death date for this William or his son William in 1790. Is there a bible record or will that supports the 1790 date?
