Dorthe Hansdotter Rasmussen

I am pretty certain that my ancestral line goes back to Rasmus Madsen who was born in Fyn Denmark in 1575. I have been looking for information on his wife Dorthe Hansdatter Oluffson Madsen for a while now. I tend to believe her father was Hans Oluffson, but can' t find any real sense of who her mother was. I have gone to ancestry, and other sources, but people tended to get the birthdates wrong as they had the child birthdate being older than the parents. One ancestry link had her father being Hans Gjertsson Busch, and her mothe being Maren Svensdatter, and I almost think that the mother's name is Maren because Rasmus and Dorhte had a daughter that was named Maren. This is a toughie, and I wouldn't doubt that no info would be available. https://www.geni.com/people/Dorte-Hansdatter/6000000005442512925
