Thank you, much appreciated information. The only thing is that again mistakes and faults are found in Postnikova.
There was a Segeyev (MC?) i Vyatka in 1892 (P#"692A"). Is he possibly the same earlier mentioned Matvei Sergeyev by Dad or? Also Matvey Sorokin seems to have assyed in Vyatka in 1851-1861 (P#692), or?
Thank you in advance.
