I sent a long reply to your private email box, and it said it did not recognize your email address (perhaps it is just screening my email address). I am very interested to learn more about your family. My husband, Fred Hewston, is the grandchild of Mary Lincoln BROWN. His grandmother's obituary said she was survived by her sister Margaret BLADES. As I researched it became obvious that there was either a divorce or more likely a death of Mr. Brown and the great-grandmother re-wed to a Mr. Northrup (Northop) and had at least one more child, Margaret "Maggie".
Margaret (Northrup /or Northrop) Blades would be your father's mother. Maggie first wed a Severet and two of the step-kids are living at home on the 1920 Alameda Co,CA census with Jerry Blades, Margaret Blades:
Pearl M. Severet age 16
and Blanche Severet age 14.
I found CA death index records for Pearl M (Severet) NEILSON died San Diego Co., 25 Nov 1997 and
Blanche (Severet) SPIERS died Shasta Co., 28 May 1997.
I found on the CA death index that Margaret (Northrup) BLADES' mother's maiden name was SMITH.
My husband has been trying to learn much more about his grandmother, Mary Lincoln BROWN who first wed Charles VARAIN and then divorced him and late in life wed John A. LANE (a man the age of her oldest son!) and had one last child, Fred's mother, Dorothy (who wed Herbert E. HEWSTON). Eager to learn more.
