Yesterday I finally found my great grandmother's birth and marriage certificates thanks to JRI Poland's website.
I've been trying to find them for years.
I knew the place and date of the marriage but couldn't find it. I decided to filter by marriage, place, year and put in her first names, Soro Feige, without a surname,
Her surname was shown as Tygres, on it's own. I knew the family were called Chencz/ Chencz Tygrys but didn't know they'd used Tygrys on it's own.
Her husband's surname went through a few changes when they got to the UK and I wasn't sure exactly what it was before.
Now I finally found that out too.
I also found her birth certificate by filtering for birth and the two years I thought she might have been born in. And there she was.
Thank you to all those involved, especially Stanley Diamond.
