I have a content type "Name", with the fields "Name at birth", "Canonical name", which ends up with tokens like [field_name_at_birth-raw] and [field_canonical_name-raw].

In then use this as a flexifield in content type "Person", with unlimited repeats (doesn't make sense here, but I'm simplifying my use case).

In pathauto I have the setting for the "Person" content type set to create the path "person/[field_canonical_name-raw]".

When pathauto creates the nodes now, it will create paths like "person/[field_canonical_name-raw]-0" etc. If I exchange the pathauto pattern to its default, "content/[title-raw]" it generates the right patterns.

I need to have a canonical name on the form, Egell-Johnsen, Paul K to create proper alphabetic glossaries in views, but I would like to have the paths on the form paul-k-egell-johnsen to enable easy interwiki linking (by adding my own person:$4 rule to it).
