Search multiple genealogy sites all at the same time by using Family Tree Searcher. This saves you time from re-entering the same information over and over.
I tested it by searching for my paternal gr great grandfather, Jeremiah Shipe and got results from nine other sites that have the same information or most of the information I input. You might get links back to some of your own research, and you might hit paydirt and find something new! There is a caveat – not all the sites are free.
