* The federal censuses consistently say she was their daughter, but also that her father and mother were born in Ireland.
* The 1910 census of Holst, Clearwater Co., Minnesota says that Elvira had had 3 children, one of whom was still alive (Nellie).
* Hattie was married in 1882 and gave Langworthy as her last name.
