Guagusan

Apologies, but the name "Guagusan" is not considered a common Russian name. Based on its spelling, it appears to have a foreign origin, possibly Armenian or Jewish (compare with "Gusan", "Guan"), though it does not follow Russian naming traditions. If you're looking for a detailed analysis specifically of this name, please clarify its exact origin or verify if there might be a typo involved. For instance, you might be referring to the name "Gusan" (Gusan-Aby, Gusan-Ibrahim) or "Guan"? Information can be provided for those names.
