I have had the most success with the following websites:
1. Ancestry: www.ancestry.com- this is an especially good place for census information. Their public genealogies are a
good way to find what other researchers have found. However, this is a starting point. Your genealogy should ideally be based
on links to original source documents.
2. Family Search Labs: http://www.labs.familysearch.org. This is an excellent free resource. Sometimes I find that a search for census information using this index finds information
the Ancestry indexes did not find. Also this site links to a lot of sources previously not easily available, like many state
indexes. The Ohio death index and the West Virginia death index from this site have given me some excellent information.
3. The LDS site at: www.familysearch.org. This is especially good for marriage information and the IGI is a useful source
of clues. There are links to other researchers' genealogies. You need to be wary, especially if you see a lot of information
with almost no details, since some researchers appear to have just made things up based on guesses.
4. Many states provide good indexes, many of which were compiled as WPA work programs during the depression. Both Indiana
and Illinois have land indexes. Illinois has some court records. Indiana and Illinois have good marriage indexes, for example.
Indiana recently put up a digital genealogy research site that I have just started to explore: http://www.indianadigitalarchives.org/
5. Land records are very useful: http://www.glorecords.blm.gov/
6. The Find A Grave site: www.findagrave.com is free and excellent. Many users are attaching extensive amounts of information
to the tombstone entries.
A change over recent years has been the use of DNA. So far McConnell DNA results show that most southern McConnells and
about 25% of U.S. McConnells have Somerled DNA (as defined on the Clan Donald USA DNA project site) which closely matches
Somerled DNA of those who are descended from Alexander McConnell, the person who died near Octorara Creek in Chester County,
PA in 1729. It is likely, based on DNA results, that Alexander McConnell had brothers who settled in North Carolina.
