Congratulations for you and your wife on the coming of your new baby daughter!
I tried googling for the name Otilia and came upon a site that may be helpful only if you speak spanish
but yes, there is a saint Otilia, patron of Alsace (sp?) the region in France. She died in 720AD. From what I can gather from this source online, The man who governed Alsace at the time wanted to have a son, but instead had a daughter and she was born blind. He sent his daughter away to a convent and she was brought up as a Christian. A bishop came to the convent "san erardo" and baptised the girl giving her the name Otilia, meaning "light of God". As he baptised her, he said "May the eyes of your body be opened to you as the eyes of your sould have been opened to you." and she miraculously recovered her sight.
Then a bunch of other stuff happened, her father ordered her back to his castle and wanted to marry her off but she ran away because she wanted to devote her life to God. Her father, I think, realised this and allowed her to come back as a maid and allowed her to be a nun. She then started a convent called "Otilburg" where she took care of any who needed, and it became a hospital of sorts. Her father then left her his castle to turn into a convent/hospital when he died. Otilia apparently offered masses, alms, and other prayers for the soul of her father and later received a vision saying to her that her works of charity allowed her father's soul to leave purgatory.
After her death, many miracles started to arise around her tomb, and there is a water source there that she made appear through her fervent prayers at a time when the convent had nothing to drink. It seems that people go to this water source and receive many miracles like the blind washing their eyes and being given sight. Her feast day is 9 August and the prayer to her (in spanish, maybe tonys or anastasios can help out) is:
Otilia: P+Ãƒâ€šÃ‚Â¡dele a Dios que nos abra los ojos de nuestra alma para ver la eternidad que nos espera, y que con nuestras oraciones, limosnas y santas misas consigamos como t+Ãƒâ€šÃ‚Â¦, el descanso para nuestros amados difuntos.http://www.churchforum.org.mx/santoral/Agosto/0908.htm
Hope this helps!
