I've been trying to track down as many of the Adams' that moved to Johnson Co, MO from Wilkes Co, NC in order help me track down other ancestors and their intermarriages within several different families that also came from the Wilkes Co, NC area.These include Wheatley, Shumate, Adams, Hays, and Roop to name just a few.
It looks like you may be getting these dates of death from the LDS FamilySearch website.Unfortunately, in the case of the children of Jacob Adams, there are several inconsistencies with that information.The dates of death for John and Isaac are one.Others are:William Hayes Adams is listed as the son of Jacob and Mary as well as the son of Reuben Hays and Elizabeth Adams (daughter of Charles Adams who is believed to be closely related to John Hobbs Adams Sr (Jacob Adams' father);another is that Isaac and Jacob Jr. both have the same dates of birth;another is that Abraham Adams is listed with two different dates of birth.
What I believe to be yet another inconsistency is the listing of Johnson Co. Missouri as the place of death for Isaac.While several of his brothers did emigrate to Johnson Co around 1830 (including two wives who were grandaughters of Charles Adams and a son of Reuben and Betsy Hays who was also married to a granddaughter of Charles Adams (my gggg grandfather and grandmother), Isaac does not appear in either the 1840 Heads of Household census or the 1860 full census.
It is possible that Isaac staked out a farm in either Lafayette Co. to the North (Johnson Co. was formed from Lafayette Co. in about 1834, a couple years after they probably arrived) or Pettis Co. to the East (Washington Township where most of them settled is in the Eastern part of the county that borders with Pettis Co).But I have not found any indication of him or his wife in either county.
John Adams on the other hand (husband of Abigail Adams) is listed in both the 1840 and 1860 census.In 1840 he is assumed to be with Abigail and in 1860 he was with his second wife, Margaret Evans.John, Abigail and Margaret are all buried in the Adams Memorial Cemetery near Warrensburg.John's date of death listed on his gravestone is January 29, 1870.
There are three main cemeteries in Johnson Co where the vast majority of these lines of Adams were buried.Adams Cemetery in Montserrat (near Warrensburg), Adams Memorial Cemetery (also in Montserrat), and Adams-Tackett Cemetery (called that because there's mostly Adams in it and it is located on a farm owned by the Tackett Family).Transcripts of the Adams Memorial and Adams-Tackett cemeteries can be found on the Johnson Co MOGenWeb site as well as the 1840 and 1860 census.
I'd be very much interested in getting what you have on the children of Isaac Adams so that I could include it in my data base.Naturally I'm more than happy to share what I have.I'd especially like to hear anything on Harvey and Chapman Hays.Harvey married Elizabeth Shumate in 1867.She was a granddaughter of John and Abigail Adams.
