How long have you been doing the research on Landroche's? I've been researching since 1997. I have met a few people along the way. Marlene (Landroche) Drouin is in New Hampshire and she has alot of information on the East Coast families. Curtis Benoit Londroche is doing the Londroche line. Alain Theroux and his father are working on Theroux dit Landroche, and their is another by the name of Joyce (Laundroche) Ball that is working on Laundroche history. I am however trying to connect everyone to the one original that came to Quebec. There is one thing I have discovered, around 1920 there were German Landroche's popping up in different states because I have found them on the 1920 Census' at Ancestry.com. I say Ancestry.com because their census is alot easier to scan than the one's at the library or LDS Centers. There are two currently living in the Denmark area. Check out my web page at http://www.landroche.accessgenealogy.com for some of the information I have collected. I am still currently adding information though. I would like to add what you have if you don't mind. Don't forget to sign my guestbook and view to see the others researching the name.
