There is some confusion regarding this couple. There we two men named Eli Chance who married ladies named Elizabeth around the same time. I believe that the Eli you refer to may have married Elizabeth Cagle. The other Eli (b. c1788, LA; d. 30 Mar 1860, Sabine Parish) married Elizabeth Allen (b. 18 Dec 1802) on 23 Apr 1818 in St. Helena Parish. They remained in LA and had 11 known children. I think I have these straightened out but there could still be errors. You can find the record citations on my web site at http://ancestry.larkcom.orghttp://ancestry.larkcom.org along with an extensive history of this Allen family. Any help appreciated.
