If you want to research your ancestors then you do not do word history as that is never going to help you...they are two very separate and unrelated things
Names are words they come from language, every name first or surname when taken was a choice, chosen from the language heard, spoken or which influenced the people at that time...... it was from the Latin language which was the language of the day in most of Europe and many European languages had its foundations in Latin...like English, French, Spanish, Italian and ALL of those languages were heard, spoken or or influenced many countries across the world when names were taken......... so you will NEVER find the country of "origin" of the person ( who happened to be an ancestor) by word hunting
The ONLY way to find out the origin of your ancestors regardless of their name is to research the real records they generated during their lifetime and that process starts at home with you and your own records
