Genelogical information on a Mary Seabrook--born 12 Nov 1812--died 20 Jan 1875 in Gowanda, NY--married Ira W. Ackley in either Erie County or Cattauraugus County, NY--mother was Elizabeth Seabrook (maiden name unknown---Mary was a descendent of the English family that originally settled Seabrook Island, SC. I think she may be descended from Robert Seabrook. She is my great great grandmother. Would appreciate any help in filling my family tree. Thank you
