I do believe the information is incorrect on the death certificate, as the dates don't line up, so I don't know how reliable that information is.

I went through photos last night and found one when the stone was legible
and it defiantly says 1865 on it. I was going by the death certificate ...

I'm looking for any information on my great great grandfather

What We have, but don't know if it's accurate

Name: Marcin Swiatowy

Birth: November 18th 1870

Marriage: to Michaelina Kaczmierczak 1890(also information on her would be great born July 16th 1874)

Left around 1893 to the United States ...
