Appendix:Latin forms of English given names
Latin was the main written language of Europe throughout the Middle Ages, despite the fact that most people used some other language in their daily life. Records surviving from this era remain of interest to many but some, such as church registers, remain untranslated, therefore a knowledge of the Latin form of common English names remains invaluable for genealogists.
Many Latin names appear almost identical to their English equivalent (often simply ending with -us/-um for masculine names, or -a/-am for feminine names) but others are quite different and not visibly correlated. Below is a list of Latin names that do and do not closely resemble their English equivalents.
List of Latin forms of names and their English equivalents
editNames beginning with "I" or "J", followed by a vowel, may be spelled with either letter.
