Here is a link to a page I did in Wikitree about the various Jennies: https://www.wikitree.com/wiki/Space:Who_was_Jennie_%27Ani-waya%27_C...
Youngwolf's wife was not named in the Moravian Journals. They had a daughter who was about 9 in 1815 (Youngwolf died of consumption 1814-1815), so that wife must have been born no later than 1790. Starr's book says she was named Jennie Taylor.
Nobody was born in Cherokee, Washington County, TN, no such place. Cherokee people were born in the Cherokee Nation. That's one of those repeated errors from place name dropdowns at FamilySearch and Ancestry (like all the people who are born in "Y" France).
Zero suggestion anywhere that Youngwolf's wife was also called Nannie, Nancy, or Nan-ye-hi (a name which does not exist in any early records, it's a modern attempt at reverse transliteration)
Whether there was a different woman called Nannie or Nan-ye-hi Conrad, sister of Gunrod is speculative. The only recorded mention of Nathan Hicks wife called her "Peg" (although she still could have been Gunrod's sister).
Starr also said that a Scots woman named Jennie Taylor came to America with a son Charles and that she later married Johann Conrad. I think this was one of Starr's major screw-ups. No one in my family line (descended from Charles Taylor) has ever mentioned any connection to the Hicks family. Charles Taylor's descendants all lived in what is now Tennessee, the Hicks all lived near the Moravians in Georgia. Starr also called Gunrod Conrad "Hamilton" and no one has ever managed to explain that.
