ROBBINS/COLLINS/SEELEY & MULLER

I am looking for information on my ancestor Mary Muller. She had 3 previous marriages/last names- Robbins, Collins & Seeley. She was from Indiana. She married a man named Maurice Wyrth or Maurice Mullaire, born in France around 1847. They lived in Union, Bergen, NJ and had 9 children- 5 sons were born by 1880 census: Francis, Fredrick, Charles, William & George. I am a descendant of Dana, who was born in 1883.
I believe that Mary had children from her previous marriages. Collins family: Charlie Collins from Brooklyn, NY. Robbins family: Al, Ada Brown, Ed from NJ, Robert with sons Danny and Walter, and Jerry.
I would love to find a living relative and share info.
