A census record, for example, might indicate from his children's ages and birthplaces that: about 1895, son John was born in NC; about 1897 daughter Mary was born in TN; about 1899 daughter Nancy was born in Tn. In 1900 you found them in Perry Co., IN. About 1903 son Joseph was born in IL; about 1906 son Robert was born in IL; about 1909 daughter Rebecca was born in IN, and in 1910 you find them in the Spencer Co., IN censuses; thus, you track the family from North Carolina to Tennessee, to Indiana, to Illinois, and then back to Indiana. Searching court records in these areas in which they lived might reveal records pertaining to where in North Carolina they came from. Having this track record together in one place can be a tremendous help.
This is what RESEARCH is--finding clues to lead you to records that prove relationships. You build your case one or two facts at a time, and base continuing research on those proven facts. If the information you are working with is incorrect, then you are wasting your time.
