Write dates as day, month, year such as 7 Oct 2001. If you have more than one date for the same event, separate the dates with a slash (/) such as 7 Oct 2000/2001. Dates can be calculated from other information. For example if you find the 1900 census shows a person as 30 years of age you can calculate he was born in 1879 (cal 1870). Some dates can be approximated. From a marriage date, you can estimate (est) a man was married at age twenty-five and a woman at age twenty-two. You can also estimate (est) that a first child was born one year after the parent's marriage and that subsequent children were born every two years after that. Again, do not use estimated dates and places if exact dates and places can be obtained with reasonable effort. For ordinances to be performed, you need to list at least an approximate year.
The names of places should be as complete as possible listing from the smallest to the largest geographical division, separating the divisions with commas. Generally avoid using the two-letter postal abbreviations which are often misinterpreted. Use an extra comma to indicate a part of the place name that is missing, such as a county. Example - Henderson, , North Carolina, USA. List the name of the geographical area that was used at the time of the event. Do not use the abbreviation "Co." or the term county.
Assumed places may be based on a place where one member of a family was born or died or lived at some time or where a marriage occurred. To show that a place may not be the actual location, it can be preceded with the word "of," for example, "of Hendersonville, Henderson, North Carolina, USA."
Our ancestors who have passed on are entitled to the same blessings we enjoy (see David B. Haight, "Linking the Family of Man," ENSIGN, May 1991, 75). As Saviours on Mount Zion (see Obad. 1:21), we have the great privilege of making those blessings available to them. "For their salvation is necessary and essential to our salvation, as Paul says concerning the fathers - that they without us cannot be made perfect - neither can we without our dead be made perfect" (D&C 128:15).
