My mother arrived today and will be visiting us for a few days. We had occasion to look through the collection of old family photos I have digitized over the years. In this one, my dad is front and center, I am to his right, and my brother is seated on my mother’s lap. As we studied the photo, my mother pointed out an interesting fact. Nearly 50 years after it was taken, two of the pictured people got married to each other. Also in this photo is the mother of the bride and the brother of the groom and they are married to each other adding further to the improbability of this image. Difficult to wrap your head around these relationships and further complicated if I tell you that the newlyweds are not blood relatives.
