No, I have no more information on the Howells. It appears Anna Rosella was sister to William Alouisus, and my information came from descendants of William Alouisus Howell (1856-1928) and Mary Margaret SAYRE (1853-1916).I believe all or most of the ones who contributed their family information are deceased.
I have disposed of all my old notes and correspondence, so I can be of little help.After I published all my Sayre genealogy in 2003, I quit doing active research.I check the Sayre GenForum occasionally to see if I can help anyone.
Just as an assumption, I would guess that the death record for Anna Rosella Borrell is correct that she was buried in Dale, Oklahoma.They were likely too poor to afford a permanent marker.However that is not to be taken as fact – just a guess.
If you haven’t already, you may see if obituaries were published for Fred Borrell in Alameda, California area 1944, and Anna Borrell in Oklahoma 1916.If so, they may have some clues for the burial of Anna.Also at times, I have been able to obtain some good clues and information from funeralhomes.
Anna died in 1916 and the family was found in the 1910 census at North Cement, Caddo, Oklahoma.You might find a Cement cemetery and find her grave there.I’m not familiar with the area and don’t know the proximity of Cement to Dale.
As for Indian ancestry, in most cases, proof is difficult or impossible to verify.It has been my experience that census takers rarely if ever marked the “I” under race, and county records called them Negro or Mulatto.Information about Indian heritage is probably more available and credible in Midwest natives than anywhere else.
Keep in mind “mistakes are made and get passed on.”I’ve found errors in records: personal, county, state, census, cemetery and bible in my past 30 plus years of research. People make errors by accident and purposely.Unknowing and careless researchers find them and pass them along. Today, online especially, you find errors perpetuated in many places.
With that, I’ll wish you fun and good luck in your search.
