Research Notes
I have not found any verifiable sources that confirm any names or dates associated with this profile. It is possible he never existed. Repositories searched include (Donnelly-2171 20:11, 12 March 2022 (UTC)):
FamilySearch, Ancestry, Geni (appears in numerous family trees, but none of those reviewed included reliable sources)
This profile was formerly connected as the father of Robert Lincoln of Hingham, Norfolk (will proved 1543). Despite extensive searches (see Research Note above), no evidence supporting this relationship has been found. Therefore, Robert Lincoln has been disconnected.
