When you visit a funeral home, introduce yourself letting them know that you are a genealogist researching your family. However, their schedule may not allow them to help you right away. If they can't help you at that time, leave a self-addressed, stamped, 10x12 clasp envelope, along with the list of names you would like them to look up. Leave only a few names for look up. Then, don't expect a reply for at least a couple of weeks.
Funeral homes have busy schedules.
If they can help you on your visit, start with the most recent names. The farther back they need to go, the more time consuming the search for that record is. Always be courteous, remembering that they also have schedules and may be interrupted to take care of their business. Offer to pay for copies, and ask if they will accept a gratuity for their search. Remember that they are doing you a favor.
