My husband's great-grandmother is said to have been from the "Yazer
Jewish Agricultural Colony" according to her husband's naturalization
petition.  I believe this was the same place as Izrailevka,
Yelizavetgrad uyezd, Kherson gubernia.  Her maiden surname was
Greenblat/Greenblatt/Grinblat/Grinblatt, and others from her family
immigrated to Argentina, though I don't know any of those names or when
they might have gone to Argentina, though apparently it was around the
same time that she immigrated (she came to the US with the children in
1901; her husband came here in 1900).

Hi again Michele,

I found this article about Rykun, it has a lot of information, and it includes this person's name:
Gesiya Mednikova.  Maybe someone from your  Mednikov family?

Sounds like my situation is similar. My great grandparents and siblings emigrated to the US from a tiny Jewish agricultural colony that was considered in the Kherson district then but now isn't. It was located NW of Odessa. (See Berdynovo on this map: http://evkol.ucoz.com/colony_kherson_en.htm). Anyway, it is said that the founders (1859) came from Podolia and Volyn but I have absolutely nothing to show that is where my famiy (BURDA) was from. It's very frustrating. 

I put together a word doc with everything I could find our about Berdynovo as well as the other  Jewish agricultural colonies in the area. This doesn't help us find out specifically where famiy moved from, but you are both welcome to see if anything can otherwise be useful to you.

Michele. My ancestors also moved from the “North” of Russia to a Jewish agricultural colony in the south in about 1840 or 1850. But we do not know where they came from when they went to the south. The name of the Colony was Sahaidak  or Saigaidak just south of Elizavetgrad in Cherson  
Gubernia.

My great-grandfather, Chaim Mednikov, as well as his father, uncles, brothers and cousins, were farmers at Rykun Colony, a Jewish agricultural colony about 30 miles from Kiev in Dymer. He later moved to Kiev where he owned a tavern. I’m looking for more information about the Rykun Colony — including where the members of the colony lived before going there. I’ve heard that Jews in Lithuania were offered farming land in southern Ukraine, but nothing near Kiev.

Thank you.
