>> A family with obvious high level access and multitudes of other items says it's him
We don't know that a "family" is saying anything whatever that means. As far as I know it was one person. I don't know what you mean by "multitudes of items." What is relevant are photos and for some odd reason we haven't seen any of them. As I pointed out, it is not uncommon for family members to disagree as to who is depicted in an old photo.
>> It looks like him...
It looks like him to YOU and the OP. To other people it does not look like him. This is a purely subjective assessment that we know collectors often get wrong. That is why we try assess individual facial features which can be much less subjective.
>> grainy images of one side of an earlobe...different angles
In the 3 side-by-side photos the center and left photos are at virtually the same angle. See post 29 for best available quality,

I am not keying in on the earlobe. The overall shape of the ears are very different and that is evident in spite of the not-so-great quality of the OPs image. It's not hard to see. As Drs. Bruge and Burger said, "It is obvious that the structure of the ear does not change radically over time" That doesn't mean that the ear doesn't grow, just not enough to be noticeable in photos until about age 70 on average.
