I can find no parents for Nellie Igou nor Jackson PArsons.I did go back and look at Mike Hudson's input of 26 Jan 04.According to Mike, El;izabeth Ann Igou, dau of Joseph, married a Gordon Parsons abou 1868 as he second marriage.
D. Thomas in 26 JAn 03input, says that Gordon and Eliza parsons are lsited in 1860 Hot Springs Co. Ark census ages 22 and 20 respectively.
I have never heard of any of the Igou's being of Native American heritage.Family legend hs it that my my ggggm (Elizabeth Painter) who married my ggggf, Andrew Jackson Igou was 1/4 Cherokee.
I have seen aall of the Igou spelling that you mentioned , plus Igoe and Igon (a common mininterpretation of the handwritten "u" on the end of the name as "n".My marriage announcement had my grandfarther's name as Samuel Igov.
Do you know in what county and/or state Nellie and Jackson PArsons were married?
