Hi - I'm a volunteer. Willing to go to the library to look this up but want to know first that you'll return to this thread and read the answer, so let me know, okay? Thanks.
Below, just in a starter search online - but didn't yet turn up the connection to the Kiowa tribe.
1940 US CENSUS Balsam, Itasca, Minnesota Address: Sand Lake Road Lester Barcus 51 born about 1889 in Nebraska - race white Willah Barcus 41 born about 1899 in IOWA - white Leon Barcus 14 born about 1926 in Minnesota - white Helen Barcus 10 born about 1930 in Minnesota - white Ida Mae Barcus 6 born about 1934 in Minnesota - white Residence in 1935: Same House
Ida's birth certificate may possibly list a tribal affiliation, but that's probably a long shot. It can be ordered at the Minnesota Historical Society BARCUS, IDA MAE Date of Birth: 06 DEC 1933 Mother Maiden Name: GIBSON Birth place: Itasca County, Minnesota Minnesota Birth Certificate # 1933-10849
Same is true of Willah's death certificate - also can be ordered from Minnesota Historical Society. I think the cost for such records is under $20. The original death certificate has more information on it than the online transcription shows. It should tell her parents' names:
BARCUS, WILLAH M. Date of Birth:08 JUL 1898 Place of Birth:OUT OF STATE Mother Maiden Name:RECTOR Date of Death:15 JUL 1985 County of Death: RAMSEY Minnesota Death Certificate# 1985-MN-019236
If you know the county in Iowa where Willah was born you can send for a copy of her birth certificate.
The Kiowa Tribe Enrollment website says "When applying for Tribal Enrollment, it is necessary that you submit an ORIGINAL state registered birth certificate along with theapplication." I presume this is already on file, if Ida and/or Willah have been previously registered.
I would guess that once a person has been verified and enrolled she would not need to reapply - but perhaps you know for sure this is not the case. If in doubt, the enrollment specialist can answer the question.
1910 US census Decatur County, Iowa William C Gibson, 54 Mitalda C Gibson, 50 Bert M Gibson Lulu Gibson, 17 Eva G. Gibson, 15 Willa M Gibson 11
1940 High Point, Decatur County, Iowa Eddie Gibson, 27 - race, white Matilda Gibson, 80, grandmother, widowed, born about 1860 in Missouri - race, white
The handwriting on original census records is sometimes hard to read. I've posted the names the way Ancestry.com has transcribed them.
Here is contact information for the coordinator of the Decatur County, Iowa, genealogy society. It's possible the newspaper article you talked about appeared in Decatur County, Iowa and this person might be able to find it: http://iagenweb.org/decatur/http://iagenweb.org/decatur/
Chronicling America is a free website from Library of Congress that indexes a few newspapers in Iowa and Minnesota. A search on the name "Rector" in Iowa brings up 317 articles, so a little more information and sifting would be needed to see if the article you need appears here (this is a long shot as this index of newspaper articles is far from complete): http://chroniclingamerica.loc.gov/http://chroniclingamerica.loc.gov/
A Bert Gibson (probably Willah's brother) married Melissa Bartlett in 1911 in Decatur County, marriage record on same website. Matilda C. Rector born in Missouri and William C. Gibson born Missouri shown on census record on link below: http://iagenweb.org/decatur/CensusDocs/1925HighPointTwpBook1.pdfhttp://iagenweb.org/decatur/CensusDocs/1925HighPointTwpBook1.pdf
Same census record, above, a Lula Gibson and Delbert Smith, probably Willah's sister.
You seem to have some of the above and also the following but at the moment I'm just throwing all this out there.
Buried in Leon City Cemetery: Matilda C. Gibson died 1945. William C Gibson died 1936. Casleton Gibson, died 11 March 1883. Bert M. Gibson died 15 July 1980. Eddie W. Gibson died 25 November 1995. Lulu Gibson died 17 January 1892. Two people named Rector are buried in this cemetery.
