Her birth record names her simply Margaret, which makes her the second
Margaret in this family. Her birth record also notes that the
parents had 1 girl who has already died, who must be the
first Margaret born in 1843.
This Janett Margaret's name is the source of much
confusion because her marriage record and tombstone clearly have
her as Jeanette or Janett M. This name confusion
matches the pattern of her sister Mary Jane.
But her birthdate on the tombstone matches perfectly with
the Scottish birth record and everything else pieces together
perfectly, so I am sure it is the same person.
In the 1880 census, she and her husband David Miller are living
with her brother James in English River Twp. of Keokuk Co.
