Hi. I have searched sites all over to find the name Gaiduk and your site is the first I have found. My father-in-law was Nikolajs Gaiduk/s and migrated to Australia from Latvia in 1948. I believe most of his family was killed in the war, and they lived in or near a town called Tukums. I also believe there is a conection to Lithuania somewhere. His father was Simons Gaiduk/s and his mother Lucia Dubrowskis. Unfortunately, Dad would not talk much about his life prior to coming to Australia as he prefered to put it all behind him. I would not be surprised if there is a connection somewhere along the line. Good luck in your search, and I will keep looking.
