Your first name of Derrien creates individuality, independence, self-confidence, initiative, and an inclination to physical activity. You are not inclined to merge your opinions and viewpoints with others, to accept compromise, or to work in a subservient position against your will. You are not drawn to music, the arts, literature, or other refinements in life, being content instead to satisfy basic comforts and needs. It is difficult for you to find the right words for such circumstances. Once friendship is established, you are very loyal and steadfast and do not tolerate gossip or criticism. Weaknesses in your health caused by this name centre in the head and could result in defective teeth, eye sight, or hearing. You are not inclined to merge your opinions and viewpoints with others, to accept compromise, or to work in a subservient position against your will. Others find it difficult to accept your domineering and, at times, argumentative manner. In your close associations and family life, there is little demonstration of sentiment, appreciation, sympathy, or encouragement. Such conditions are aggravated by your appetite for heavy foods such as bread, potatoes, or milk, which promote the formation of mucus in the system.
