The first part of the name comes from nąwáčak, "fort, fence," from ną, wood; wa-, "an action that"; čak, meaning unclear, but has something to do with sealing things off. So nąwáčak is "wood involved in an action to seal something off." Nąwáčagᵋwįga is from, nąwáčak, "fort, fence"; -wį-, a feminine gender infix; and -ga, a definite article used in forming names. So her name means, "Fortress Woman," which is certainly consistent with a Bear Clan name.

She eventually parted from her husband. It is not clear whether she took her daughter with her. The Chicago Daily Tribune gave a sensationalized account of her departure, claiming that the Army forcefully separated married couples, which is certainly not true. Butterfield (387) gives a less dramatic account: "He subsequently married another Winnebago woman; they had no issue, and when her people migrated west, she concluded to go with them — so Rasdall and his Indian wife cut a blanket in two, each taking a part, the Indian mode of divorce." This neatly avoids dealing with matter of their shared child by denying that there was such a person.
