U is for unnamed. It is sad when you find unnamed male or female in your family line. You usually find this in the BDM registers when searching for births of a couple. Sometimes you find it in a family bible. One of my Connor families has three unnamed males between 1862 and 1870. I cannot begin to comprehend the sadness that must have accompanied these births. Other families have named children who died soon after birth.
So to all the unnamed angels in my family file I hope you are looking down on me and smiling over my genie research.
