Execution Date, Acknowledgement Date, and Recording Date
A deed may have the date it was signed, the date it was acknowledged, and the date it was recorded. Make certain you indicate which is which. They can be clues in some cases. A husband and wife executed a deed in 1814 in Kentucky and by the time it was acknowledged a month later, the wife is listed as a widow. This allowed me to approximate the date of death for the husband.
