Hello Ted, Isn't genealogy interesting? If it was easy, it wouldn't be any fun! I wanted to tell you that both those marriage listings are probably for the same Hulda, and the first one didn't take place. If it had, she would have been Hulda McCormick when she married Elias Jackson Martin. Especially if Nora had been born during that marriage; if Hulda was a widow, she wouldn't take back her maiden name. Also, my greatgrandfather took out a license to marry in 1896 in Christian County, IL. He never did marry that woman, and instead married a short time later to my ggrandmother. Both of those "marriages" are shown in the Illinois Marriage Index at the State Archives site. The marriage index for each county has the licenses taken out, but there is no way to know if the marriage was actually celebrated unless there was a "return" of the license for registration by the celebrant. Some marriages don't have a return, if the celebrant failed to bring it back after signing it.
So, either 1, or 3 are likely in your above, very wonderful, list of possibilies, but 5 is always a possibility, too.Elias is 4 or 5 years older than Hulda, so he possibly had a brief first marriage.In 1900, Hulda has had 5 children and 4 are living, yet none of them are at home. She has only been married 25 years, but 4 living children are all married or out on their own. In 1900, Jane is 9 months old. Most healthy women in the 19th century were having their children approx. 2 years apart. Jane is 9 months old and May is 2, probably near 3 and born ca 1877. Hulda and Elias married in 1876, so that works. The next child would be born in about 1881, and I think 4 would have been born by 1883. Since child 5 is not living, it could have been born anytime between 1883 and 1900, as Hulda is only 45 in 1900. That would leave the youngest living child about 17 years old, and old enough to be either married, or working away from home.
I think the best way to find out about the children is to try to get obituaries from the Coles County Genealogical Society, check cemetery records for the Martins to see who is buried with them, and check probate records for both Elias and Hulda Martin to see who their heirs were. Elias Jackson Martin died in Charleston, Coles County, IL 10 November 1924 and Hulda Martin died in Charleston, Coles County, IL, at the age of 81, on 8 January 1936. These are from the Illinois State Archives site; Deaths 1916-1950. The Genealogical Society also has family files and histories and maybe someone has left information on this family there.
Hope this helps, even a little bit! Barbara Volunteer
