Hello, one of my grandmothers was Elizabeth Adrian, 1780-1841. She married (Johann) Peter Knecht. She lives in Germany, Rheinland Pfalz / Hessen (Aschbach,Schmalenberg, Trippstadt). Her father was Johann Adrian (1738-1806). The father of Johann was Nicolai or Nikolaus Adrian. The name "Adrian" also was written "Aderjan". I think it means the same. The Adrians were shepered (?) Sorry, my English isn´t so good. When someone ist surching for Adrians in this regions, I´m afraid to hear from you.
