WorldConnect can give researchers clues as to other families that might have been a part of the same migration trail as your ancestor. This approach does have limitations:
- You may find the same people over and over
- You will only find people who have been located by a researcher
- You will only find people whose descendant or relative has bothered to enter them
- Some submitters have incorrect information
That said the database can give you names that could be helpful. When I performed this search for natives of Harford County, Maryland, who died in Coshocton County, Ohio, I saw two relatively unusual last names that also appeared in one branch of the family who left Ohio for Fulton County, Illinois.
Clues from WorldConnect should be used as clues.
They should not be used as fact.
