Leonard Genealogy - and Iron In America


As noted (Leonard Y-DNA), y-dna analysis has proven that there are a number of separate and distinct Leonard lines.  We did not descend from the same common ancestor in the past 20,000 years.  Surnames came into use about the year 1200 AD in England.  It is likely that Leonard or some variation on it (e.g., Leonhard in Germany) was chosen as a family surname from St. Leonard who lived about 500 AD and was the patron saint of slaves, prisoners, and horses.  In medieval times, saints days were celebrated.  Individuals celebrated the day of the saint after whom they were named much like we celebrate birthdays today.  Churches were named after saints, such as St. Leonard's Church in Bilston, England, as were local landmarks (e.g., St Leonard’s Forest in Sussex, England), and in some cases, the Leonard surname may have been picked up from the local church or landmark.  Consequently, Leonard surname lines emerged across the breadth of Christendom.

Below  are some of the Leonard lines and branches identified in my family research to date:

These are not all the Leonard lines. There are many more to be discovered and researched.
What would be helpful to all would be the identification of the y-dna haplogroup and subclade of each of these lines, as well as the Y-STR pattern of markers for each branch of a line.   That information would make it possible for direct male Leonard descendants to  narrow the range of possibilities as to their ancestry to focus their family research.
