This is an example of unproven/undocumented information being included in the Wikitree system. When looking at other sources (Ancestry, FamilySearch, and the like) there are numerous conflicting listings for Laurence Tyler and Laurence Tyler, Jr.
There needs to be more research into the actual lineage, but most likely, someone with access to original records will need to weed out some of the speculative and conflicting information surrounding Laurence Tyler.
