Good morning! I'm glad I clicked into the site this morning and found your notification.
The current house on that site is not the original house, but it's on the same lot and possibly on the same foundation as the house indicated on the soldier map. You can see that it precisely aligns with the soldier map in my satellite overlay. The current house was built in about 1900 by John Henry Stretz (most likely one of your ancestors) to showcase his skills as a brick mason. The house and retaining wall in front are still beautiful examples of his polychrome brick work. John Henry had a son named Leonard who owned the house when I was a kid, and who spent some weekends there. I think he lived in Kansas City. I never met Leonard, but my parents and uncles and many people of their generation all knew him.
The Stretz property is long and narrow and extends all the way from Morgan Street to the bluffs overlooking the railroad right of way along the river. In a fence row on the West side of the property is a circa 1920 - 25 marker where John Hayn and Ferdinand Kimball died in the
2nd Battle of Boonville. (I think Kimball died later of his wounds. His name is misspelled on the marker, and given as "Gimble.")
More recently, a marker was placed on the back of the Stretz property commemorating the site of Hannah Cole's fort after the War of 1812. Cole's fort was probably on the site of the old hospital / Fair Grounds, but it was very close to the Stretz property. Can you tell me about this marker? It wasn't there when I was a kid. I imagine it was placed by someone in your family.
If you look closely on the soldier map and read earlier posts to this thread, you'll see that a number of soldiers were buried on the back of the property. My uncle knew of oral tradition about these graves and told me they were in the eastern fence row of the Stretz property. The soldier map shows them a little more west of the fence row.
My boyhood home evolved to its current appearance around 1904, and I am certain it was altered and built out from the "bones" of the Lilly farmhouse. When my father had some remodeling done after WWII, signed and dated plaster was uncovered, indicating much earlier construction.
My older brothers remember the place as a farm. I remember it more as a developing residential area. My friend and fellow member here,
@Boonslick, conducted a survery of historic sites and buildings in Boonville during the 1970s. He has more information about the property. I called him as soon as I saw your inquiry, and I've given you the high points of his survey report. That neighborhood is one of the most history-rich areas in the entire town and county. Feel free to send me a private message about the property.
