Just ran across this online and found it odd. Can any members of the Carpenter community elaborate on this map? According to the text size used on this weather.com map, Carpenter is actually larger than some of these other area towns. I’m not sure when they found this map—1896?—but I can assure you the “towns” of Merton, Keefton, Carlton, LaDelle, and Bloomfield do not exist. And if Merton does indeed exist, how come it gets a larger font than fellow non-existant neighboring town Keefton?

After your interesting debacle, I weather.com’ed my hometown as well. These are either former towns, or recognizable local locations. Example, around Watertown, Weather.com lists “Tunerville” (Bar and two houses east of Goodwin, household knowledge in the area), “Kones Korner” (Gun shop/convenience store & a house, again common knowledge in the area), and “Alsville” (Extinct convenience store, now hollowed out artifact of an Amaco station.
I bet your parents will know exactly what these locations are. I am guessing the colonies are hutterite colonies?
Bloomfield…isn’t that by the Wipf’s place on the way to Huron? Pretty sure it used to be a town, right? Very interesting find indeed…
Bloomfield and LaDelle used to be towns…Jordan is right, Bloomfield is where Iky Wipf lived. Merton is a township but I’ve never heard of those other two. If your map had gone a bit further south there would have been Shamrock Colony, too.
