It appears James Siver married Sarah McAllister and they had daughter Luella. James died in the war and his brother, William, married the widow Sarah. William and Sarah had children Adora, Elmer, Jesse, Merrit, Olive.
I found a document I will upload that is about the guardianship of Luella. Names Sarah as her mother and approves William Siver as a court appointed guardian. He seems to have adopted her! A great brother!!
The other Sarah is the same person, but the profile manager has an incorrect name imported via gedcom
