Answer:
The best way to start in genealogy is with yourself. Write down your full name, your birth date and place, and, if you're married, your husband's or wife's full name, birth date and place, and the date and place of your marriage. Then continue by listing your parents names, birth dates and places, marriage date and places, and, if deceased, their death date and place. Next, you would list your children's and siblings' (brothers and sisters) same information. After that, list your parents' siblings' information as well as their parents' (your grandparents') information. If you don't know any of this information, ask that person or a relative who would likely know. Keep doing this with each person's parents and siblings. There may be more information you will want to collect, such as occupations, military service, etc. That's genealogy.
You should also borrow a book on basig genealogy from your local library and read it. Then consider joining a local genealogy group that is welcoming of beginners, so you can talk to real people about procedures and resources.
