Yet another family line where I am stuck....!

My Great Grandmother was Amy Elleanor Stowell. Her mother was Margaret Stowell. Margaret died on the 2nd April 1926. Margaret also had 2 sons William and John. I believe that she lived into her 70's so I think she would have been born about 1850's. I have not been able to find out her husbands name - can anybody help. The story my Grandmother always told was that the family were from Ballastowell (Tower farm) and that at somtime our line of the family was done out of the farm . (I have read it was passed out of the family from Edward Stowell in the 1800's to the Kerruish family). What I can't work out is how we fit into the picture (I wonder if I possibly decend from one of the brothers of Edward Stowell???). I believe that there has been various research carried out about the genealogy of the Ballastowell Estate as it was in the name of the Stowells since the late 1500's. If anyone one can help I would be very much appreciated, especially as to any information about Margaret Stowell and her Husband. (I assume Stowell was Margarets married name).

Thanks again
