Hi Audry, In the book "The Past and Present of Rock Island County, Ill, 1877" could you please see if there is a Marmaduke ABBOTT. He was my GGGrandfather and came from Tipperary Ireland before 1860 and settled in Coal Valley, Rock Island Cty.,Ill. with his wife Margaret, Sons Wm. Henry and Marmaduke Jr. and daughters Fannie, Louisa and Isabella. Marmaduke Sr. must have died before 1878 as RI County clerk has no record of his death and they have records back to 1878 only. Thank you for any help, Bev Hannigan, Houston, Tx.
