A very useful reference work which I bought because I needed to translate Latin from various sources like wills or birth, death and marriage records, or manorial rolls and court records. As you travel further back in time, Latin was the commonly used language and a lot of English words are descended from the original Latin or are still used eg ipso facto, ibid, NB etc. This book is aimed at the Local or Family Historian whether amateur or professional genealogist. It is proving a very useful resource book and comes highly recommended.
