Hearts Bound Together by Henry B. Eyring
For those family historians who are LDS, there was a superb talk titled Hearts Bound Together given by Elder Henry B. Eyring in the April General Conference. Elder Eyring's focus was specifically on the duty of LDS members to do their genealogy research. (Latter-Day Saints believe in doing sacred ordinances for their deceased ancestors who did not have the chance to perform them while they were alive. In order to do this, they need to know who their ancestors are...hence the need for genealogy work.)
Here is a portion of his talk...
"You begin by doing simple things. Write down what you already know about your family. You will need to write down the names of parents and their parents with the dates of birth or death or marriage. When you can, you will want to record the places. Some of that you will know from memory. But you can also ask relatives. They may even have some certificates of births, marriages, or deaths. Make copies and organize them. If you learn stories about their lives, write them down and keep them. You are not just gathering names. Those you never met in life will become friends you love. Your heart will be bound to theirs forever.
You can start searching in the first few generations going back in time. From that you will identify many of your ancestors who need your help. Someone in your own ward or branch of the Church has been called to help you prepare those names for the temple. There they can be offered the covenants which will free them from their spirit prisons and bind them in families—your family—forever.
...After you find the first few generations, the road will become more difficult. The price will become greater. As you go back in time, the records become less complete. As others of your family search out ancestors, you will discover that the ancestor you find has already been offered the full blessings of the temple. Then you will have a difficult and important choice to make. You will be tempted to stop and leave the hard work of finding to others who are more expert or to another time in your life. But you will also feel a tug on your heart to go on in the work, hard as it will be.
As you decide, remember that the names which will be so difficult to find are of real people to whom you owe your existence in this world and whom you will meet again in the spirit world. When you were baptized, your ancestors looked down on you with hope. Perhaps after centuries, they rejoiced to see one of their descendants make a covenant to find them and to offer them freedom. In your reunion, you will see in their eyes either gratitude or terrible disappointment. Their hearts are bound to you. Their hope is in your hands. You will have more than your own strength as you choose to labor on to find them."
I think Elder Eyring gave some great reasons and good encouragement for us to keep doing our genealogy, even if we aren't LDS.
