Capt. William Carter of Surry - Changed DOB

For Geni purposes, it's probably even better to use 1599 without the "Circa" box checked.

Geni has a very specific meaning to the Circa flag on dates -- it means precisely +/- 5 years. You can see that in the resulting age estimate. In this instance, with the birth Circa set, the age shows as (51-60) based on death in Aug. 1655.

By unchecking it, the age estimate changes to (55-56) ... much closer to the "reference" age 53 as of March 1653.

A good Geni guideline could be: if the date is known +/- 1 year or so (e.g. most U.S. census date estimates) do NOT check the Circa box.

However, if the date is a multiple of 5 (e.g. xxx0 or xxx5), then -- unless you know there are other reasons, such as birth order of siblings -- DO check the Circa box, since that'll probably give a better age-range estimate.

If you know the 'actual' date range, then use the "Between" option to define the dates. The estimated age will adjust accordingly.
