Any update on this thread in the past 2 years? :)
I am tracking my Nightingale lineage and, like you, ran into a wall with Frances beign widowed. Edwin's father must have died between 1865/66 and 1871 for the census to show widowed. Edwin and Blanche's marriage certificate listed Frances and Samuel Nightingale as the bride's parents... I was assuming that the Head of Household Everitt's maintained raising Edwin. Any information is greatly appreciated!
