I have a unique first name in my family tree, I've not come across another Jacqueline or Jackie. But I've come across a few unique names for females on my Scottish side. Although most of the first names are quite common, it's the middle names that make them unique. Names such as Agnes Gilchrist Danskine and Jemmia Findlay Danskine. What a wonderful way to leave clues for the family researcher, by adding maiden names as middle names.
