Girls born in the early morning

In my culture, the baby girls who are born in the early mornings are known as mangli. There's a saying for such girls that their marriage happens to be late (which I have seen to be true as my aunt married when she was at late 20's) and their married lives are disastrous. Can you give any hadith reference in regard to whether this has any basis or not? A well known astrologer too commented on such girls by saying that they have a suffering married life. Please answer me about this astrologer's comment and about the girls being born in the early morning.
