While reading though the Death Notices I started to see words that I had never seen before.The first being ultimo. Ultimo means in the month preceding the current one. Somewhat confusing, but I've since gotten used to reading it and understanding what it means.
The other new word is instant. In this case instant means in the current month. Sometimes there are some inconsistencies where near the beginning of the month the notice states "On the 15th instant", but the newspaper date is before the 15th.
These smaller newspapers can be a great way to find ancestors. The Catoctin Clarion can be found online at the Library of Congress for the years between 1871-1922. The search function doesn't work that well but it is a start. A lot of times one can find children that never made the census records since they tend to give age and parents names in the notices. Marriage notices are also listed in each of the newspapers which many times states the officiant's name and place of marriage. Occasionally the bride's parents are also listed.
There are many issues of the Catoctin Clarion missing, especially the first few years. I have not found an online edition for the Valley Register. Typically the Marriage and Death notices fall on page 3 for both newspapers, though occasionally they fall on the 2nd or 4th. Rarely are there no notices published at all.
Hopefully you can find some of your relatives in these local newspapers and fill in some holes or break some brick walls.
