Kindly thank you for getting back and for your update.
I knew this resource you have mentioned: http://www.locatefamily.com
I tracked before the list of people you provided. Most of them have passed their way already and I couldn't find their ancestors reading their obituaries. I wrote even an e-mail to Punnichy village major and canadian congress of ukrainians President in Saskachewan region... but received no responce.
Some of the rest of Muzichuk's from there, the 3rd's, 4th's 5th's generation...and so on - have moved to USA, to California, Florida, Michigan, MA Midleton and so on...
I have found few of them in social networks such as facebook and myspace, but didn't manage yet to set up a single contact with them.
I suppose this is because of.... they rare using social networks, and on the other side - I don't have suficient funds to top-up skype account in order to give them a call to landline telephone number.
Will much appreciate any advice about how to proceed with this issue. I'm in Ukraine/Lviv at the moment.
