Be sure to include spaces for the names of the parents and extra spouses of the Father and Mother. Another extremely useful form is the Pedigree Chart. Use it to record your own, personal ancestry. The most commonly used charts contain spaces for 4, or 6 generations of ancestors. A stack of group sheets and Pedigree Charts should accompany you on every library visit.
Some libraries have a big enough budget to provide free forms.
Feel free to use them, but do exhibit some restraint. The taxpayer dollar you save may be your own. Armed with these paper tools you can collect and organize family information. Then, use these documents as a guide for computer input. Once the data is entered, you could throw the paper forms away.
