-ilie/-ilia was a fashionable name ending in the 19th century (with names like
Ottilie, Emilie/Emilia, and similar names ending in -alie/-alia like
Nathalia or
Amalia). The motivation of the inital Mat(h) is more difficult to pin down---in fact impossible without additional information about parent names or godfather names. Besides
Mathilde, candidate source names include
Matthias,
Magdalena (c.f.
Maddalena),
Martin or
Martha (in regions where a pre-consonantal r is dropped).
