Future of Microfilm Machines

We have recently acquired a new microfilm machine at the Archives called the ST ViewScan. This post will highlight some of the most interesting features of this new technology.

The new ST ViewScan at the archives.

Background

Canon, the manufacturer of microfilm reader machines, has discontinued their micrographics line. This means that the traditional reader-printer machines are no longer available for purchase, and soon enough, we will not be able to find parts to service our older machines. Instead of the traditional lens and projection method of older microfilm machines, the most recent technology in microfilm readers is a system involving a high-powered digital camera. The image from the camera is viewable on a computer monitor, and the program allows for a larger number of options and functionality than the older machines. This is the future of microfilm machines!

Browse Tab

The Browse tab in the program lets the user adjust the image, much like the "wheel" in the lens of the older machines. However, inside this tab, the user has a higher degree of control over how much is "zoomed in" and how much is "focused." The user can also easily adjust light levels and even use the "Straighten" tool to level out the image!

Cropping Tab

The Cropping tab in the program lets the user crop an image to only what they want, and eliminate the unnecessary text. By simply clicking and dragging boxes around content, the user can select just the specific article they want.

Saving

The images can be saved to a USB in various formats (PDF, JPEG, TIFF, etc.) Most useful is the Searchable PDF option which uses OCR (Optical Character Recognition) software to create a PDF which is searchable using the "Find" functionality in Adobe. (Click and hold Ctrl + F on your keyboard to "search" a document that has OCR capability.) This will make locating important names, dates, or locations in your research that much more effective!

Conclusion

The new ST ViewScan microfilm machine is an extremely useful piece of technology which gives users much more tools at their disposal than the older microfilm readers. Step-by-step instructions are available at the terminal and staff are more than happy to give users an orientation to our newest piece of equipment at the Archives.

Genetic Genealogy

The Lambton County Archives recently held a presentation on genetic genealogy where presenter Carolyn Abraham explained the science behind using DNA testing to reveal secrets in your family ancestry. Carolyn is a former medical science reporter for the Globe and Mail and author whose recent non-fiction book The Juggler's Children: A Journey into Family, Legend and the Genes that Bind Us has been shortlisted for the Governor General's award for 2013. (If you are interested in obtaining a copy, please contact The Book Keeper.)

 

Presenter Carolyn Abraham.

Carolyn explained during her presentation that this book chronicles her personal experience with genetic genealogy as well as the how-to's and potential issues involved in this avenue of genealogy. There were always family mysteries surrounding both of Carolyn's great-grandfathers and the birth of her daughter around the time of the human genome project spurred her to research her ancestry.

 

Types of DNA Tests

As Carolyn explained, the "genome is a portal to the past" in that it can reveal where in the world our ancestors came from and how we are related to others. There are three basic DNA tests which all require a cheek swab:

1) Mitochondrial DNA Test: since mtDNA is passed from mother to children, this form of testing is limited by the fact that only women pass this DNA on. mtDNA does not change quickly from one generation to the next, so it is a powerful tool to reveal if people had a common female ancestor. This is limited since it can only reveal the commonality, and not when that commonality occurred (i.e. could be five years ago or 500 years ago.)

2) Genome Scan Test:  scans chromosomes from mother and father to provide a breakdown of ethnic percentages and ability to connect with relatives within approximately the last 5 generations.

3) Y-DNA Test: available for males only since the Y chromosome passes from father to son, this test can reveal ancestral paternal lines and allow you to connect with genetic cousins and also reveal your haplogroup (which area of the world your ancestors came from.) 

For all of these tests, after you send a cheek swab to the company, they analyze the DNA and compare it against other samples in their database. They will then contact you with the results (which vary depending on which test you pay for) but generally, they can tell you if you have genetic relatives (those whose DNA is close to yours meaning you share a common ancestor) and your ethnic background.
.

Possible Ethical Issues 

When you are testing something as personal as DNA, it is important to be aware of possible ethical concerns right from the beginning. There is always the potential to find that a relative you may be testing is not genetically related (i.e. father is not the biological father.) This issue is so common that software has been designed to catch these "false paternities" which has been estimated to account for about 10% of tests. 

DNA testing can reveal results which affect the entire family.

It’s your obligation to give people the full information and potential results before they agree to contribute to your research. This not only impacts them, but their children and the wider family. DNA testing always has the potential to open up closed doors, so you should establish who you will be sharing information with at the beginning of your research.

Recommendations for Further Information

Carolyn recommends the company Family Tree DNA and suggests that those seeking more genetic genealogy information check the website of the International Society of Genetic Genealogy. This non-profit group promotes the use of genetic testing in genealogy, and has many free resources and links on their website.

Conclusion

Testing for DNA can help reveal secrets in family trees and fill in the blanks where paper records do not exist. It is a powerful tool to supplement traditional archival research. As always, the staff at the Lambton County Archives are here to help you with this research and we are also interested to hear your stories of genetic genealogy usage.
