Two things:

The Hesch who's getting married on August 8th in Arcadia, Wisconsin is Joel, son of Dennis, who's the son of Leonard, son of Valentine...Mathias' oldest child. Got that?

Roger sent a short narrative he wrote in 1995 about the Waumandee Heschs--this part deals with how and when Valentine (his grandpa) died:

"In 1936 or about, Val and Lena purchased about 140 acres in section 35 of the town of Montana (about a mile from their farm). This property had 2 houses on it as it originally consisted of two farms. In 1937, they rented this farm to Ted and Edna (Hesch) Weaver. In 1942, Ted Weaver died and Edna continued to farm with her brother Leonard until 1943 when he married. Leonard purchased the personal property from Edna. At this time, Edna and her two boys moved back on the home farm and lived with her brother Rudy until his marriage to Lucille (Dworschak) in 1947.

Meanwhile, Rudy had purchased the personal property on the home farm from his dad, Valentine. Val had been renting out the extra home he owned on Leonard's farm, and in June 1946, died at that site while showing it to a couple from Winona who wanted to purchase it. He died of a heart attack; his grandson Roger was with him at the time of death".
