Abeyance is a different matter then Albanny. Its when there is no one clear heir to a title. It doesn't happen very often, as is usually only the case when a man dies with no sons, and his heirs are female. Unlike sons, when the eldest son is the designated heir, with English peerages, there is no designated heir among daughters. If the peerage can be inherited by a woman, all daughters have equal claim. Either the other claimants die out, or one of the claimants appeals to the monarch, to have their claim recognized. It doesn't happen in Scotland, because with Scottish peerages, eldest daughter is recognized as the designated heir, if no son exists.
And yes there has been a move for these claims to be eliminated after 100 years.
Albanny was deprived of the title. Which is also different from foreifeiture. Deprivation allows for the male line heir to still lay claim to the title. Forefeiture would mean the title would be extinct and could be reused. There is no time limit on deprived titles.
