Can two parents who do not have freckles (ff) have a child with freckles?

I know nothing of the specifics of this particular trait, but assuming inheritance follows classic mendelian genetics no they cannot.

According to my source, freckles are dominant.

But the question then is, how many freckles do you have to have to qualify as "having freckles"?

One or more? isn't that the definition of "having"?
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
