An excellent suggestion as the indexes are insane. I have the index for Volume one on this website
http://freepages.genealogy.rootsweb.ancestry.com/~sbrad/ I have only a few names from Volume 2 and also there are other names in the index from my family but if there is a page number it is from TSFIA. The index includes a birth year and spouse to help differentiate between individuals. I hope to get the other volumes indexed at some point but it was such a huge task with volume 1 (the only volume I own) that it is hard to get seriously started with only having access to online copies of Vol 2 and 3. Very tedious. I'm currently not working on the website but hope to finish/expand it in the future. I am almost done upgrading/fixing my ancestry.com family tree so maybe the next project will be some Volume 2 and 3 indexing. That way people will be able to at least check the online indexes to see if their people are mentioned in the books.
