Hej neighbor! If you're in the area formerly known as New Sweden, you should check out Philly's American Swedish Heritage Museum located in FDR park down by Novacare and the stadiums!

There are still plenty of traces of the Swedish in the region, including several old churchs. Gloria Dei, 929 S Water St, Philadelphia, PA 19147, is the second oldest Swedish Church in North America. It's a national historic site and its graveyard would probably have what you are looking for.

99% sure it's currrently closed due to COVID, but it's definitely worth a look once things get better.
