We have analysed the charts of yours and that of your girlfriend. As it can be seen from the charts, the relationship with those in the family on both sides would be not so normal, especially with your mother.
Health analysis of your parents could be looked in to from their birth charts and not from yours. Overall married life would be normal and progressive in nature. Karmic connection on a lower side can be seen in your chart but not found in the chart of your girlfriend.
You can go ahead with the alliance as there are no negative connotations implied in the charts.
