Hi Barbara. Here are a couple of suggestions.
1) Spend a little time going through the help file and it's index, and become familiar with what's there and how it's indexed. There's quite a bit of info, but it's sometimes hard to find. I think there has been some recent work on trying to improve the index, so give it a try.
2) You can also search previous G2G discussions, using key words in your questions, by typing the key words in the "Search G2G" box at the top of the page.
3) Some members have had a lot of success with using Google to search this site. If you type "site:www.wikitree.com" (without the quotes), and then the search parameters, in the Google search box, the results will show only the relevant matches at this site. More detail at

I'm sure others will have a lot more ideas. Good luck.
