AN65 Yep I do believe you have the true family .Havin compared the 4 cens you posted it looks to me like chas,ada & phoebe is the only p,o,b that remain constant most other details change about between each cen As you would partially expect .Aswell as the 1891 cen showing 2 kids as twins yet these or any of the other generations dont show any more twins.
Personally my conclusion is that Sam is very likley to be Len .It is so like other familys of this type & time, Constantly trying to avoid giving any details to the governments IT.may be the closet to the truth that can be found
THANKS FOR YOUR TIME
