There are few things in genealogy that are more important than finding vital records for each and every person that you want to add to your family tree as you go back through time. You may want to see how far you can go back, but you should never do that at the expense of not being sure you have the right people. What would happen if you put years into your research only to find that you went the wrong way? You would have wasted all of that time. Make sure you find vital records so you are sure before you move on.
The vital records that you can find about most people that you want to add to your family tree are out there somewhere if you know where to look. These include records of marriage and divorce, birth and death, and a few other things in some cases. There are some cases in which records were destroyed in fires or lost forever, but most people can find the vital records that they need for their family. They name people in the past, and verify they are indeed in your family.
Vital records for those that are still alive are very hard to find. Some sites that deal with genealogy records will not list vital stats and records for privacy reasons. When someone is still living, you can get your information elsewhere anyway. The records you find through these sites are going to be for the members of your family that have passed on. Along with vital records, you may find things like property deeds and immigration records that can verify or dismiss what you have.
Searching these sites is often helpful. You can decide if you want to pay for a membership through some of the bigger sites, or rely on what you can find through the free ones. The ones that have no membership fee are that way thanks to support from those that use them, and the research of volunteers. Most of them have accurate information, but not nearly what you can get through the larger sites.
If you are telling yourself that you must find my family's vital records, but you don¡¦t have a lot of time to search, you can always find new clues through a source that can give you what you need in due time. Sometimes, this can come up in minutes if you are willing to pay the fee. This is great for your very first clues, or when you think you have hit a brick wall at any other time.
