<human>: How can I find out how many people are in my family tree?
<bot>: You can start by researching your family history. Look up records of births, marriages and deaths to get a better understanding of your family's history. You can also look for documents such as census records, military records, or immigration papers that might provide you with information about your ancestors. Additionally, there may be websites or genealogical societies that specialize in helping people research their family trees.
