Because of so many questions and a few goofy ideas floating about,
here are some age restrictions and duties in 18th century VA generally
(and usually NC), as I understand those to be.  If you have different
interpretations, please tell us of such, yet let's not debate the
matters.

Always remember also, that ages and allowable actions were often
within the discretion of the VA County judges and Colonial Council in
order to cope with unusual conditions/situations.  In addition, any
legal incapacities, such as felony and poor farm convictions,
determinations that one was a lunatic or imbecile, and women who were
restricted by marriage often were considered differently.

At age 14 for males (age 12 for females),  such could

Select their own guardian
Be an apprentice to learn trades
Be tried and punished for crimes
Show property lines to processioners, if known
Sign contracts (though seldom done, because later renunciation was
allowable)
Witness documents as to who/what was seen, said & heard
Give testimony in a court proceeding (after qualification)
Act as executor (but usually with an "of age" co-exec)
Bequeath personal property by will

At age 16 males,

Were tithable
Served as militiamen voluntarily or otherwise
Act as a processioner if church appointed
Assume possession of their real estate

At age 18 males

Could be licensed to practice a trade/calling
At age 21 for men (18 for women), they could
Be married without consent of parent/guardian
Release a guardian from duties (automatic at marriage)

At age 21 for men (and usually women), they could

Be eligible for public offices (usually)
Serve as jurors on grand, petit, or coroner's juries
Vote (unless there was a property requirement)  File and defend
actions in court
Hold title to real estate
Devise (transfer) real estate by will
