Martha E. Baker

I am looking for information about Martha E. Baker usually listed as being from Ohio but on a few occasion she is listed as being from Pennsylvania. I'm guessing she was born about 1830 +/- a five years.  She married a Michael Dwyer (born in Ireland and died in the USA.)  Martha Baker Dwyer and Michael Dwyer lived in Michigan where at least 2 children Mary Dwyer and  brother John Dwyer.  Mary and John eventually married and mover to and died in Duluth Minnesota.  Mary Dwyer Oven was born in MI on July 30, 1868; she married George H. Oven and died in MN June 8, 1957. John was born in MI on June 15, 1872; he married Emma Oven in MI and died in Duluth, MN on Dec 21, 1912.  Siblings George Henry Oven and Emma Oven married Mary Dwyer and John Dwyer respectively.
