Yes, the Solon were a subtribe of what were later called "Manchu". It is quite notable that while most tribes started to fall under the Manchu identity at some point, the Solon were often mentioned separately. They first resisted Qing empire-building fiercely, but once subjugated made some of the best warriors of the Qing. They were even feared still in the 1860s by the Taipings, in a time when most of the Qing army had become a caricature of itself. By the time the Qing fell, all Solon, Chinese, Korean, Russian, Mongolian, Hui and Manchu Bannermen were classified as "Manchu" and by now they are probably truly sinicized.
