This is not a required field but the more information you can provide, the better. While an exact address is potentially more information than you would have, or want to share with the world, if the general location (town, region of the country) of your honoree is important to who they are, this is where it can go.
On memorials, if someone lived in one place but died somewhere else, you should put the place of residence.
For group memorials and celebrations, we offer the ability to include multiple locations. Just fill out the first location, click Add, and then fill out the new fields that appear and click Add again.
