POSTED by CJ Christensen, 30 Jun 2010, cousin once removed of Myrtle.
See below for Ebba and Wilford Johnson Timeline and Death Certificates for Ebba and Charles Rognon.
Myrtle and Marguerite were daughters of Ebba Johnson Rognon. They were born to Ebba and her first husband, Peter Johnson, but later took the last name of Rognon, Ebba's second husband. Ebba and both daughters died of TB. Since Ebba's mother died young, could it have been of TB also?
