I may be able to help you. My husband's grandfather, Adam Thomas Breitweiser, was born to parents Nicholas Breitweiser and Catherine Breitweiser from Hesse Darmstadt, Germany. He had brothers John L. Breitweiser and George Breitweiser and Jacob Breitweiser. There were two sisters Catherine Breitweiser and Mary Elizabeth Breitweiser. The parents settled in Westminister, Maryland. John L. stayed there and raised a large family. George and Adam went to Ohio and married women from there. Adam's first wife died and he married the second time to Mary Jane Feighner and had one son Paul Breitweiser. They moved to Anderson, In. This was my husbands Father. Jacob Breitweiser went to California and was murdered there. We think he left a family, but have not looked for them as of yet. We do have a picture of George Breitweiser. Do hope this is your line. Please let us hear from you. There are so few Breitweiser's.
