Ancestry is celebrating it’s 15th birthday by giving you free access to one collection for 15 minutes each day for 15 days. Here is their press release…..

Over the next couple of weeks, we’re giving you free access to some of our most popular collections from around the world. Better yet, we’re helping you make the most of them with a series of quick tutorials. All you need is a spare 15 minutes every day!

From October 1st-15th, we’re making another top collection free every day. From Australian electoral rolls to World War I documents, you’ll have access to all kinds of records, many of which are usually only available to our Worldwide members.

With each free collection, we’ll provide a tutorial right here on our blog. These helpful articles will give you a taste of what you can find in the records, and suggest some quick tricks you can try in a quarter of an hour.

Don’t worry if you miss a day – after they become available, the collections will be free right up to the 15th. And of course, we’ll leave our tutorials up indefinitely, so you can keep coming back and trying our tips.

By the time you’ve finished, you’ll have several new places to look for your ancestors, and some great tricks to help you uncover their stories. Just remember to keep checking this blog every day for the latest tutorial.
