My great grandfather is Felix Silvestrov Liaudanskas married to Sofia Gorodeckas Liaudanskas. Because their children were born at the earliest 1882, I am assuming that Felix was born around 1860, and apparently the same for Sofia. I have been searching for the father of Felix and there appears to be a missing link between Silvestras Liaudanskas born 1775 and married to Magdelena. So I am curious if you have any information about this Silvestras that you wrote born "before 1877". As you say he is the father of Felix, that would mean that he would have to be born before 1840.
