He died thirteen years after the marriage, and, after having remained a widow two years, the woman married again.

These children were all born in Valencia, between the fifteenth and thirty-fifth year of the mother's age, and at the time when the account was written she was thirty-five years old and pregnant again.

Of the children, 47 by the first husband and 52 by the second were baptized; the other births were still or premature.
