My grandfather's German cousin joined this same order in Louvain with the express purpose of following Fr. Damien to Molokai. He was not a priest, but a brother of the Congregation of the Sacred Heart. He arrived on Molokai in 1895 after Damien's death, but he served the lepers for 45 years, the longest serving missionary on the island. He retired in Hololulu and never contracted the disease.
It's amazing for me to discover this link to Molokai in my own family since I have been fascinated with Damien deVeuster since I was a small child. Only after I began family history research did I link up to my German ancestors and their progeny. Which is how I discovered this link. Later I found a small 2-sentence item in the local newspaper which mentioned my great-grandfather receiving a letter from his nephew on Molokai about the mission there. Since then I try to convey to my younger relatives the importance of serving and how their cousin served the lepers of Molokai. Today's children really need to learn about true heroes.
What a fantastic heritage you have in the story of your grandfather's cousin! Blessed indeed was he!
Bump to your idea of passing on the notion of serving others! God bless you!
