[Ger-Poland-Volhynia] Volhynia origin

[Carole]

I have found on an immigrant list at Grosse-Ile my grandfather's sister, Sofia Ruchotzka (sister of Ludwig Henkel) and her husband Alexander.   It lists their place of origin as Londska Zirda, Colonia Olgin, Russie.  I know they came from Volhynia to Canada.  Can anyone translate this place for me?  

Thank you!
