Time differences

[BadgerLordFiredrake]

In the Redwall Family Trees in the wiki, I noticed that Squire Julian Gingivere is related to Ungatt Trunn.  The Squire was in Matthias (I think)  and Ungatt Trunn was in Lord Brocktree (again, another guess).  How many years apart are the books?

Ungatt Trunn was in Lord Brocktree, and his descendant Squire Julian Gingivere was in Redwall.
You can consult this topic to see the chronolodgical order of the books, which gives you an idea of how long the period between those books was.
