I am researching my great-great grandfather, Salomon (Zalman) Mingelgreen. I know that the surname is originally Mingelgrun (with the German umlaut) but has also been seen spelt as Mingelgrin. I am currently stuck on him, and what I know is that he is from Austria (specifically Brzysko, Galicia), was born around 1859 - 1862 but I am unsure of when he had passed away. He married a woman named Lena/Lona (whom I have been having problems gathering information on her as well) who was also born in Austria around 1864. Together they had 5 children (Nathan, Jacob (my great-grandfather), Clara, Arthur, and Isidore). I am trying to find information about Salomon's parents specifically -since I have hit a wall trying to get any further back than I already have been able to.
If anyone has any information about Salomon(Zalman) Mingelgreen(Mingelgrun/Mingelgrin) AND about his parents, or any information about Salomon and Lena Mingelgreen would be wonderful. Or any information or guidance about how I can further find information about my great-great-grandfather (his wife) and his parents.
