This will be the last Lesser Known Saint in this format, where I talk about three or so saints, maybe I will change the focus on to Orthodox saints or something like that.
Erkembode (late 7th-early 8th century)
With Erkembode nothing is known what we do know is mostly surmised. He was an Irish monk who traveled to Saint-Omer, France where he lived in the monastery where he was later named Abbot, he was eventually also named Bishop of Thérouanne, the capital of the region. Erkembode was the name of the see where the monastery was located. He was bishop for 26 years and is buried in the cathedral of Saint-Omer. Erkembode’s tomb became a popular shrine, which is visited by depressive people and parents of crippled children. The parents often leave tiny shoes to aid in the recovery of their children.
Padarn (6th century)
Padarn was another bishop-abbot, but he lived in Britain (Wales and Brittany) to be exact. Padarn is a unique saint as his hagiography mentions Arthur, King of Britian. As the story goes Padarn is one of the seven founding saints of Brittany and he establishes a monastery there, Padarn travels around and eventually makes it all the way to Jerusalem where he and his travel companions David and Telio were ordained bishops by the Patriarch of Jerusalem. On this trip Padarn got tunic and it became something that King Arthur wanted to have.
Lidwina (Lydwine, Lydwid, Lidwid, Liduina of Schiedam)(18 March 1380-14 April 1433)
Lidwina was a Dutch mystic and is thought to be one of the first documented cases of multiple sclerosis ever. At 15 she fell while Ice skating and and broke a rib, biographers say that at this time she became paralyzed except for her left hand and bleed profusely. After the fall she never recovered but became progressively worse over time. Lidwina took to fasting continuously and also shed skin, bones and parts of her intestine, her parents keep these in jars and they smelt sweet, there are documents which explain this. She is the patron saint of figure skaters.
