The owner of the name Zaitseva can rightfully be proud of her ancestors, information about which is contained in various documents confirming the trace left by them in the history of Russia.
The basis of the name Zaitsev was the worldly name Zayats. This name was added by the child's parents to the name he received at baptism. This name was used more often than the baptismal one and was fixed for a man for life.
The presence of the second, mundane, name was a kind of tribute to the ancient Slavic tradition of the two names. Its purpose was to hide the main, church name from "evil spirits" and "evil spirits".
