I started my ancestry research by creating our family tree. Yes, that same thing you last did in grade school. You can do this on paper, but it will be much easier to do it digitally with the help of a laptop or a smartphone. The most popular websites are ancestry.com, familysearch.org, and myheritage.com. When adding a member to your tree, be as detailed as possible, do include the middle name, maiden name, and nickname, then add their birthday, birthplace, date & place of death, and marriage details if applicable.
