I created a descendant report that included the marriage of second cousins, Josiah Matlack and Sarah Ellis. Sarah’s mother was Amy Matlack.
Amy Matlack was number 14. Two of her children, Levi Ellis and Sarah Ellis were numbered 28. Number 27 was skipped. When I go further down in the report Levi is 27 and Sarah is 28. This is the only place I could find a problem with the numbering.
