Founder-linked collateral branch
The family history places Louella in the branch descending through Hugh Poston of 1835, identified as a younger brother of Andrew Poston.
Marriage and convergence
Her marriage to John Henry Poston is treated as the point where the close Andrew-linked branch and the direct Poston surname line rejoined in one household.
Archive evidence
The Poston Family Archive preserves a compiled lineage chart that places Louella between Hugh Poston II and Lawrence Chalmers Poston. The Archive explicitly labels that chart a research map rather than independent proof of every parent-child relationship.

Documentary evidence and archive links
The linked Archive records are documentary or compiled research aids. Where an Archive page labels an item as a research guide rather than primary proof, this page preserves that distinction.
