In trying to trace my wife's ancestry I notice that you are an expert on the Bickerstaffs. The information I received from my wife's grandmother, Martha Louise Bickerstaff, before her death in 1994 is as follows. Martha's paternal ancestry is William Lealon Bickerstaff, b.Feb 1878, Arkansas; Herschel Bickerstaff, b.7-Jan-1849, Alabama; Robert Judson Bickerstaff, b.28-Nov-1828, Jasper, GA; Robert Bickerstaff, b. 1770, PA; Johnston Bickerstaff, b.1720 at sea, England to America; William Bickerstaff, b.1694, Ormskirk, Lancashire, England. Could you please tell me if any or all of this information is correct or partially correct or totally incorrect before I try to trace this branch of the family further.
