This is all really close, but no cigar yet.
My grandmother's name was Selma Laqua Ollmann born 9-22-1898 in Falkenberg or Tillowitz. Her parents were Karl and Pauline/Paulina Laqua.
My mother remembers other siblings of my grandma named Laqua as August, Fritz, Ida, Karl who was married to Clara all around Falkenberg or Tillowitz from the 1920s to the 1940s.
Any help is appreciated.
