My name is Jon Ellis Monday. My mother's maiden name is Marjorie Meinecke, and my grandfather was Ellis Meinecke. We were all born and raised in Northern California.
My grandfather had three girls - no boys, so the name stopped there. But, I don't have much information on that line of the family. My great-grandfather was Frederick (sp?)Meinecke who married Henrietta Edith Massberg. As far as I know they only had two children: Ellis and Kay, both born in San Francisco.
Please let me know if this fits with any information you have.
