Re: Thomas Sageman-Mary Ann Elizabeth Pannell
Thomas Sageman and his first wife Frances (Fanny) Challen had a girl named Mary Sageman born November 14, 1849. Could be the Mary Sedgman you mention having a child in 1874.
The Pannells Alfred and family who drowned in 1869 were undoubtedly related to Mary Ann Elizabeth Pannell. Alfred Pannell was the son of William Pannell who also lived at Strathroy. I think William Pannell may be Mary Ann Elizabeth Pannell Sageman's father.
