I believe that my ancestor, Harriet Frances Fannin, is Akalis’ granddaughter.But I don’t have proof.Harriet was raised by Robert Craig Fannin and his wife Sarah in Sonoma County, California.But her death certificate lists Jonathan and Margaret Fannin as her parents.Harriet’s birthplace is sometimes listed as Missouri (which matches with your data) and sometimes listed as born in a wagon train somewhere between Missouri/Iowa.
My assumption is that Robert is the brother of Harriet’s father Jonathan, but I don’t have proof of that.
Robert has a file at the National Archives due to his service in the California Volunteers in the Mexican American War.There’s a letter in that file (I have a copy) asking about a bounty land warrant for both Jonathan and Robert, and listing Jonathan’s father as Akalis Fanning (I’m not sure whether Fanning instead of Fannin is a mistake of the clerk or a sign that this is around the time that the name changed to Fannin).This is in San Jose the 29 Nov 1852 and refers to an earlier letter sent in 1851.The letter states that Jonathan has been dead since that earlier letter.
Robert was born in Illinois the 20 Feb 1830, but I don’t know where.Presumably Clark County given the dates from the Black Hawk War?
The other trace of Akalis that I have is in the 1852 California census in San Jose.Living by himself with no trace of Robert.The original has been destroyed and the microfilm is just barely readable.It lists Akalis’ previous place of residence in Virginia.There is a DAR transcription of this census that is quite good.
