Looking for information on the GABER family that settled in Pittsburgh, PA area. Michael GABER is my great-great grandfather

Michael GABER [ ? – 1918]. Michael died in the great flu epidemic of 1918.
Wife: Anna (SPEICHER) GABER (Had 6 siblings: Lena Link, Margaret Luffy[had 2kids: Sister maura and Marlene], Clara Young, Edward, Nicholas, and George)

Michael and Anna had 8 Children, one of which was Flora Ann Gaber, my grandmother. Suspect GABERs immigrated from Germany or a German speaking country. Any information would be helpful.
Thanks,
Gretchen Pastorek
