I'm an amateur genealogist, working on my family history. I've been trying to track down a couple of elusive relatives and determine if they are indeed mother and daughter. I've looked for a birth certificate or birth registry entry on free websites like FamilySearch.org and the Clerk of Cook County (Illinois; the daughter's birthplace) website, and on paid sites like Ancestry.com and Heritage Quest, but I haven't had any luck.
I have been able to narrow down the year in which the daughter was born, and I checked the catalog of the Family History Library in Salt Lake City. What I'm looking for, the "Registers of births outside of the city [Chicago], 1878-1894," is only available on microfilm. Luckily, I can have that reel of microfilm sent to my local FamilySearch Center at a nominal cost, and I can look at it there.
So what is my point in telling you this story? Sometimes the information you need is not available online, and you have to e-mail, call, or go to the library to get it. Come see us or contact us at the Dick Smith Library - we're glad to help you!
