I have run across a strange situation with Morris Francis (Frank) Townsend and his wife Lena E. King Townsend.. He is listed on the 1930 Census as living with his daughter Erma Townsend Elmore in Johnson County Missouri as Widowed. Lena is listed with her son Earl in Sedalia, Missouri and also as widowed.
Name:Morris F Townsend
Birth Year:abt 1858
Relation to Head of House:Father
Name:Lena E Townsend
Birth Year:abt 1863
Relation to Head of House:Mother
You see that every so often with separated or divorced couples. I would guess this is what happened. Are they buried in different cemeteries or together. And widowed is often used to mean div or separated, esp by women.
Not sure if this is at all f interest, but have at it: a book on eBay
