The origin of names has lots to do with the genealogical research. Afterall, you can only track back a relative through it’s name, be it first or last name. Some face the problem that names develop and change their spelling throughout the centuries in a way that they are almost not identifiable anymore. It’s the case of Brilhador which the original writing was Briatore. In this case you can perhaps explain the origin and developement. More mysterious are last names such as Gotobed, Brushit and Tellme. Can you explain those or you also think it’s only the product of human creativity?
