4. Archives.com This is also a pay to use site. It is a bit different than Ancestry.com but I have found it valuable for searching newspapers and city directories. They are now partnered with Fold3, formerly Footnote.com, and you can search for and order vital records from their site. COST
7. nekg-vt.com Northeast Kindgom Genealogy is a great site if you are looking for information on anestors in Northern Vermont. Vermont seems to have the best records of any state I have encountered, maybe because of its small population. Anyway, this site has many local records, newpapers and other data, it's really be a help for me and they also have forums. The owners will also assist with questions, at least they have helped me out. You can use the site for free, but for a small fee you can get a membership to use the search engine, it is well worth the money. FREE/ COST
8. freebmd.rootsweb.com This site is a search site for the BMD, births, marriages, and deaths in Britain. It starts in 1836 and can tell you in which quarter of the year the event took place. It also gives you a reference number so that you can order a copy of the record. I was able to get several marriage and birth certificates for ancestors from Manchester, these records list parents which is especially helpful if you don't know who they are! It is very easy to order certificates from the GRO, the general registrars office, they take credit cards so you don't have to worry about currency. FREE
I will post more to this list as I have time so check back.
