Put a date of birth even if it is a guess, you can type in abt. say your g grandfather was b 1840, his mother may have been married at age 20, so she may have been b abt 1820. His father may be abt the same age or a yr or 2 older. Also, at least put in a state (abbreviations ok eg: MA). You will most likely get more hints and you may hit the jackpot.
Read those images in census records you may discover your g grandmothers maiden name because her widowed mother or an unmarried sister/brother is living with her. I found 4 generations in a census living together under one roof. NY State census 1855,1865 etc not only has the people, but what county or state they were born in, what their house was built from (log, wood stone etc) and how much it was worth, if they owned the land and how long they had lived in that town, what they did for a living. In the back of those census it lists them and how much land they owned, the value, what they grew, how many horses, cows, sheep or chickens they owned, & how much was harvested.
Cemeteries, all States have their own genealogy sites, most of which have cemetery listings. Find-a-grave is a good source and free, you will have to sign in with a password. If you type in just the last name, pick country, state and counties pop up automatically in USA. Every person with that last name will come up. If a woman’s maiden name is listed her married name will be listed first (say you are looking for Jones, and an aunt’s first name was Rachel b 1842, you may find White, Rachel Jones b 1842 d 1915.). Oh ! they had a child who died at 4 yrs10 mnths. 3 days that you didn’t know about. While your researching how about adding your own ancestors if you have that information? Be sure to connect married folks and their children.
When using Ancestry, you can use “wild cards” when searching, the * and ? for first and last names, at least 3 letters must be used, eg: Johnson John* or *son, or Jo*n. You cannot use these if you are using soundex.
Stumped by some information about your grandfather? Most towns have Historians call them on the phone or e-mail them, some will charge, others will go out of their way and be happy to help free of charge. Do you have information that they don’t have? Pay it forward and give it to them.
