Van Leuven (Houven?) in Burke\Craftsbury VT ??

Hi. I am trying to find information on something my family has been stuck on for YEARS. My grandfather's sister was not able to solve this before she passed away. The issue is a woman named Mary (do not know her maiden name!) whose first husband was a Leonard Jones lived in Craftsbury or Burke VT. They had a son ( first name Lewis\Louis? middle name Horace?) by the last name of Jones who married a Rosina M Young. Leonard supposedly died in a logging accident and that Mary married the neighbor Josiah Allen 3 years later. If I remember correctly, cant find the death certificate online but seems like the Jones son he died in St Johnsbury VT. The mothers name on it was listed as Mary Van Houven but I have seen another person on my match list with last name spelled Van Leuven. When I contacted that person he said "I dont know anything about anyone named Mary from Vermont but my relatives are from Illinois and moved to Ohio." and then said something about the Reginarids\Reginars (Habsburg Dynasty). However, my grandfathers sister before she died said she always thought the spelling of Mary's name was Van Leuven and that her father's name was Hezekiah and mother Betsy\Betsey but she could NOT ever find out for sure or any other information. I've taken this up since she died and a schoolmate that was born in Netherlands (native Dutch speaker) also tried to look and he can't find anything. So either we have something incorrect? Or the spelling of the surname isn't right? We'd LOVE to be able to solve this!! I don't think Mary had any children under the name Allen but both her and Josiah are buried in the Burke Hollow VT cemetery. If that helps. Any help would be SO appreciated!! I am super stuck on this. Thanks in advance!
