Here's something I found by Googling for Jacobus: G o o g l e's cache of http://www.geocities.com/Heartland/Meadows/3011/NGS.htm National Genealogical Society Quarterly "Signatures, Penmanship, and Name Variations Identifying Reverend Mr. Jacob Ware" by Kay Rockett Volume 86, No. 3, September 1998 <snip> "This pair of documents raises yet another research consideration: name variations. The 1675 matriculation register identifies the newly enrolled student as Jacobus Ware, adding (in Latin) 'of All Souls College...' The 1679 graduate signs as 'Jacob Ware (of All Souls College).' The previously cited biographical note in Foster's alumni directory cites the 1675-79 student as James Ware. All three names were interchangeable in that era. Latin was the language of the scholar at Oxford in the 1600's. Students signed their names using the Latin form--in Jacob's case, Jacobus and Jacob. However, Jacobus was also used then as the Latin form of James. Foster, when he compiled his directory two centuries later, translated the student names back into English. During that process, he chose the wrong translation for Jacobus--rather than the less-common Jacob, he used the popular James for both the student and his father." I guess that answers that--look for both! Debra Radack
