I don't really know much about translations but played around on the computer. "roku" came up as "year" in Polish. And "W" came up as "in".
Could Rodytosy and Pomsrta be towns/areas? Couldn't find any words close to these.
Here's my wild guess:(born) in Rodytosy year 1865, (died)Pomsrta 2 January(?)year 1933.
