This is not by chance but more dictated by conventions that many adhered to in the 1700s to 1800s. Biblical names were not uncommon also, reflecting a family commitment to a certain faith, as were names that honoured Royalty or influential people such as Napoleon. In general though, family names honoured people in the direct family line. Naming conventions vary according to culture with some adopting slight changes according to gender, such as Francis and Frances. Others, particularly last names, reflected geographical names such as Victoria and can often be seen in the addition of “ton’ to the end of a place name indicating the place of origin. Occupational designations such as Miller stemmed from as early as the twelfth century.
With first names the following British conventions may assist in determining further generations:
Later children were given the names of other relatives of both parents, especially if they had died young or had no children of their own. If a child died in infancy, often the parents would name the next child of the same gender with the same name as the deceased child.
