Could you please scan copies of her death certificate and obit and email them to me?
M P Steadman is Asa's brother Emmanuel P. "Manuel or Manny" Stedman (or Steadman). The name Scherman throws me a bit. His first wife was Anna Roberts who died 22 November 1834 in Starksboro. He married Phoebe Jenkins Hoag as second wife 14 June 1835 in Starksboro. Phoebe was born 10 May 1804 in Vermont and died sometime after 1870. Manny was in Winona County, MN in 1860 and 1870 census. I have not found him or Phoebe after that.
I guess it is possible that Anna Roberts was not his first wife, but I do not have an earlier marriage record. Scherman (more likely Sherman or Shearman if thinking that era in Vermont. Scherman is more a German spelling that might be more common in Minnesota.) might have been a first wife as I do not have a marriage record for Anna and Manny. Anna is supposedly a daughter of Stephen Roberts Jr. and wife Mary. I have no details on either of them.
Phoebe Jenkins Hoag might have been born Phoebe Jenkins but I have not found records of either her birth or family.
With Phoebe, Manny had a daughter Anna, born about 1836 in Vermonth. She married a Homer Lyman sometime before 1859 in Vermont but were in Minnesota sometime between 1862 and 1867.
I have now linked Phoebe to Manny in my database based on your death certificate reporting. (I can easily assume that by 1915, the informant was not alive when Phobe's mother died so had no direct knowledge of her.) This will be included in my next update to my on-line database.http://www.johnlisle.us
