Wealth generates paperwork. Deeds, lawsuits, contracts, account books, purchase records, education, etc. all produce records of our past. The wealthier you are, the more paperwork is produced. The more paperwork produced makes it easier to find and follow our relatives and their past. We follow their extensive paper trail.
Backtracking the common is the challenge. Finding and following those who have left little to follow is the task of many family historians. You’ll need determination and tenaciousness. You may have to get creative. You will need the help of others. Reach out. Ask. Collaborate. Be open. Be grateful.
