Madison Township is the largest township in the State of Ohio. In a single generation, (1800-1840), it has been a part of Trumbull, Richfield, Chapin, Geauga, and Lake Counties in Ohio.
For ease of research, I have been putting the early ancestors in its current location, the "Madison Township, Lake County, Ohio" category, while retaining the date-correct county in the location slot on the individual profile. This keeps all the settlers in a single location no matter what exact year they arrived in Madison Township. So, if you are looking for a settler who bought land in the Connecticut Western Reserve along Lake Erie, you might find them in the Lake County, Ohio category: https://www.wikitree.com/wiki/Category:Madison_Township%2C_Lake_County%2C_Ohio
I may find that creating a Connecticut Western Reserve category would be helpful as I move farther along in profiling the setters but, so far, county and township categories have been sufficient.
