Hi Sheri ~
Not sure if the following info is new to you. I checked several resources for you and came up with the information below:
1920 Federal Census -- Antigo, Langlade Co., WI:
HULL, Reuben, age 70, b. CAN., parents b. CAN.; to U.S. 1849; naturalized 1860, occupation: engineer.
(with) HULL, Amy, wife, age 54, b. Wisc.; father b. NJ; mother b. (illegible).
Sheri, also living in Antigo twp, Langlade Co., that year (1920) was a man who may be Reuben's brother (or cousin):
HULL, Aaron, age 75, married, border, b. CAN; parents b. CAN. to U.S. 18___ (not filled in); naturalized 1860.
The same census also included a Reuben J. Hull, Jr., age 15, who was single and living by himself as a "roomer." He was b. Wisc., as had been his father, according to the census taker.
Your Reuben and Amy's marriage is recorded in the Wisc. Marriages Index as follows:
Reuben HULL and Anna E. ALBRIGHT married Oct. 9, 1880, Jackson Co., WI.
So Anna (aka Amy) may have been a Jackson Co. native).
That should give you a little something more to go on.
