Today, many of the top genealogy sites announce their new databases on their blogs - with surnames. Other blogs are devoted to research on particular ancestors - so a search of genealogy blogs could help you find repositories of otherwise unknown family tree information.
Search for ancestor surnames, genealogy topics, locations, or relatives.
Blog Search is Google search technology focused on blogs. Google is a strong believer in the self-publishing phenomenon represented by blogging, and we hope Blog Search will help our users to explore the blogging universe more effectively... Blog Search enables you to find out what people are saying on any subject of your choice.
You can choose to search posts from the last hour, last 12 hours, last day, past week, etc. so that you don't duplicate your searching effort.
You can also subscribe to 'blog alerts" to automate your blog queries for surnames and ancestral towns. You will receive an e-mail when your query keywords are found in a blog.
To create a query so that only genealogy blogs are searched, be sure to add ~genealogy to the query along with your surname or other keyword.
