I want to make sure I am understanding this. The facts:

1. Doris Lloyd and Robert Lee Lloyd own tenants by the entirety and convey a life estate to their son Robert Larry Lloyd and upon his death to their other sons Ralph Alan Lloyd and Robert Lee Lloyd Jr. as tenants in common. 

2. Robert Larry conveys his interest (said interest being a life estate shared jointly with the grantees) to the grantees Robert Lee Lloyd and Doris Lloyd.

3.  Robert Lee Sr dies, no will recorded.

4.. Doris, Ralph Allen and Robert Lee Jr convey to Ralph Alan , no mention of life estate.

5. The will is recorded for Robert Lee Sr.

My brain has been fried lately, so excuse me if this seems obvious to you.  From the above I'm getting that Ralph Allen Lloyd owns the property by himself, without anyone else having a life estate, that everyone conveyed their interest.   Robert Larry did not join into the deed in #4 because he conveyed his life estate in #2, voiding the remainder going to Ralph and Robert Lee Jr.

Sound right to you?
