in this group we mostly focus on Silesian Voivodeship, Stronie Śląskie is placed in Dolnośląskie Voivodeship. I recommend You to take a look at the map of Voivodeships of Poland in your free time. There is a great group https://genealodzy.pl/ in which people are looking for their family all around Poland.
I’ve got a question: are you sure its about Stronie ŚLĄSKIE? It may sound oddly but there is a small village next to Lanckorona named Stronie. I’m sure that from this area and in this period of time people from this region emigrate to USA (in my example from Skawinki next to Lancorona, thats why I know Stronie exists). But I may be completely wrong.
I also recommend using https://geneszukacz.genealodzy.pl/ where you can find informations about your surname (there are partially indexed entries from record books and registry offices, not all its made by people interested in genealogy in their free time).
Both recommended sites are free to use 🙂
If you nedd any help feel free to ask.
