Wasted some time barking up the wrong family tree - there was ANOTHER Fred A. Plummer in Michigan, but he was born ten years later in Raleigh, North Carolina.

This means the information on "your" Fred A.'s parents *may not be correct*.

This looks promising:

The guy who took the 1860 Census misspelled the name "Plumber":

1860 > INDIANA > MORGAN > MONROE TWP

* Malinda (sic!) Plumber 28
* William A. 7
* Thomas A. 5
* Mary L. 3
* Victora (sic!) 2
* Elizabeth C. 7 mo

Information in the 1860-1870 range is very hard to get, because Fold3 has grabbed up so much of it (Civil War-related, don'tchaknow?).

Your boy had a bunch of half-siblings:

William Plummer and Matilda Plummer are on the Big Tree...but on a line from Levi Plummer, Sr. that is known to be compromised at or above him.

Genuine descendants of Thomas Plummer II, of Prince George's (only son of Thomas Plummer I) should belong to the Y-DNA haplogroup G (deep-testing will probably show G2a3b1).

Descendants of Levi Plummer, Sr., test R1b1a2, by both of his wives (so it's not simple confusion over who married whom).
