Greetings Galina,
I am researching my family tree on my mother's side..
The information I have (from family records) is as follows.
Ivan Petrovich Kriklowenky (1800- ) had the following children:
Maria Ivanovna Kriklowenskaya who married Sergei Lisovsky. They had 3 children, Anastasia, Yulya and Sergei
Alexandra Ivanovna Kriklowenskaya who married Havriil NIkolayevich Orlov. They had one child, Mikhail who married Olga Nikolayevna Tebenichin. they had 8 children, Ivan, Alexandras, Anfisa, Mikhail, Havrill, Klauida, Kira and Irina.
Matvey Ivanovich Kriklowensky who married Ekaterina Illinishna Simokova. They had 2 children, Anna and Zinaida.
Petr Ivanovich Kriklowensky who married Pavla Semyonovna Strelstova. They had 6 children. Maria, Petr, Alexandra, Klavida, Antonin and Mitrofan.
Mitrofan is my great grandfather. He married Varvara Onisimovna Belekonj. They had 3 children, Mikolai, Petr and Leonid. Mikolai (1900-1972) was my grandfather. He married Maria Dmitrievna Oliakova (1901-1988) and they had 1 child, Halyna (1927-2019) my mother.
Galina, I can send you a report of my research if you like.
