Sec. 6. "Root of title" means that title transaction in the chain of title of a person:
(1) that purports to create the interest claimed by the person;
(2) upon which the person relies as a basis for the marketability of the person's title; and
(3) that is the most recent to be recorded as of a date at least fifty (50) years before the time when marketability is being determined.
The effective date of the root of title is the date on which it is recorded.
