Fortunately genealogical research does not require a conversational ability with the Latin language. To do adequate research in old records, you probably would need to know some basics and a few hundred words. From my standpoint learning Spanish at an early age has been of immeasurable value in doing Western European research. With the aid of a dictionary, I can usually read most of the pertinent Latin in church records. It is not uncommon for me to find a mixture of Spanish and Latin in the Catholic church records of the 1800s.
In my high school days, Spanish was considered an easy language to learn and so I took French and German. I was a miserable student of both languages even though I took two years of French and two years of German. To this day, I still cannot understand why I took second year of both languages when I did so poorly in both. My language career started when I was called as an LDS missionary to Argentina. This began both my interest in languages, as such, and my ability to learn and speak them. After obtaining a B.A. degree in Spanish and a Masters degree in linguistics, I spent two more years in Panama. However it was not until I taught five years of Spanish at Mesa Community College in Mesa, Arizona that I really began to learn the grammar. I would not expect that you would want to go through all this just to do genealogical research.
Now back to Latin. One slight complication of the Latin language is that it borrowed a lot of words from Greek. It also has a significant number of Germanic loan-words and a measurable number of words borrowed from Arabic. Languages derived from Latin are spoken throughout southern Europe and are the national languages of Spain, Italy, Romania, France and portions of many other countries. English has a heavy influence from French due to the Norman invasion in 1066.
When approaching any foreign language in your genealogical research, it is important to understand that you do not have to learn to speak the language to do research. In Catholic Church records for example, you will find the same phrases repeated over and over again. In my opinion, you will have much more difficulty reading the handwriting than you will in translating the language. Fortunately, because of our common European heritage in the Latin language, there are a lot of helpful online resources for translating enough Latin to do research. You can always use Google Translate to go from Latin to English (or any other of its 60+ languages) or English to Latin.
Here are a few websites I would suggest for basic reference on the Latin language.
- Orbis Latinus
- Latin Genealogical Word List
- FamilySearch.org Learning Center has 38 classes on Latin related subjects
- Latin Genealogical Word List from Genealogy.About.com
- OpenLearn has several free Latin courses
If you would like a book on the subject, there are lots of Latin textbooks. You can probably find one, as I have, in a used bookstore or online on Amazon.com. Here are a few for starters:
