Curious about similarities in Adoptive parents.

I have noticed a few odd similarities between my adoptive parents and the adoptive parents of some friends. My adoptive mother was quite sickly with very bad allergies, dry skin and asthma. Her side of the family were involved with the masons and her sister had given up a child for adoption years before my adoption. My adoptive father was a catholic with something against god and the church as well as an alcoholic and smoker. Both adoptive parents smoked when I was very young in the house. I developed all these afflictions as well. I am curious to see if anyone else had any of these type of similarities in the people they were given to or perhaps other things I haven't thought of.
