Sorry for not having replied sooner, but have been rather busy of late following-up on some leads.
For your information:
My ??? HELON, B. Abt 1852 married Katarzyna SUSIDYK, B. Abt. 1852; Katarzyna had a sister Anna SUSIDYK who married Jan MISTECKI.
Parents of Katarzyna and Anna were Michal SUSIDYK and Maria KOS.
Parents of Jan were Jan MISTECKI and Pelagia KUNCIO.
Wonder if you recognise any of these?
