Apparently the profile is locked (else I would've done it myself), but the display name ought to be changed from "Henry de la Pole, 1st Lord Montagu" to "Henry de la Pole, 1st Baron Montagu". His title would've explicitly been "Baron Montagu", which would then be simplified to "Lord Montague" whilst in use. But the term "Lord" is ambiguous, since it could refer to any rank of peerage, and many titles have changed. For example, the Earldom of Cornwall was later replaced by the Duchy of Cornwall. All holders of those titles would've been called "Lord Cornwall" in actual use, whether they were one of the earlier Earls or the later Dukes, but due to that very ambiguity, it is important to specify their actual rank in Geni profiles.
For whatever it's worth, this particular Baron Montagu was my 13th great-grandfather.
Thank you.
