Notes:

From Wilbur Hanson Kalb
As the eldest uncle of Jacob, I thought I knew all the nicknames and abbreviations of his name in certain languages but, when I read the German Wikipedia article “Jakob ( Name )”, I saw that you did get it right.  The Kirchenschreiber [ church scribe ] didn’t get drunk on the Kirchenwein [ church’s wine ] and messed up after all.  “Cob” was indeed a nickname in German for Jacob, similar to today’s nicknames, Koebi in German, Kobus and Kobe in Dutch, Coob in East Frisian, Köbes in Kölsch ( the dialect of Cologne ) and Köbi in Alemannisch ( Bavaria, Swabia, Vorarlberg and the Tyrol ).  So we’ll go with Cob as Jacob Thomæ’s nickname.  As for that abbreviation after his surname, “f.” is short for folgendes, German for “following”, to show that Cob Thomæ and his bride, Anna Schübart, were following Balthasar Schübart and his bride, Barbara Pfeffer, to the wedding altar.  The name “Eucharus” is actually spelled here as “Eucharius” ; it has the same ending ( ij or ÿ ) of the Latin word for son, “filius”, in that 1613 baptismal entry of Heinrich Thomä, the son of Lorenz.  And it’s meant to honor the Eucharist.  Therefore —
The German and Latin transcription, with the first line in Latin :

Dom[inicæ]. 1. et 2. post Epiphan[iam], p[ro]clamirt [ with the symbol for “pro”]
vundt 25. Janūarÿ Copūliert worden

Balthasar Schübart von Hellingen,
vndt Barbara, Veit Pfeffers tochter.

Hr Erhard [ = Ehrenhaft ] Cob , Thomae f[olgendes]. Vndt
Anna Eucharÿ Schübarts tochter.

The English translation :

1st & 2nd Sundays [ 10 and 17 Jan. ] after the Epiphany [ 6 Jan. 1608 ], p[ro]claimed
and [ Monday ] 25 January Married were :

Balthasar Schübart from Hellingen,
and Barbara, Veit Pfeffer’s daughter.

Mr Honorable [Ja]Cob Thomae f[ollowing]. And
Anna Eucharius Schübart’s daughter.

In the Gregorian Calendar of 1608, the Epiphany fell on Wednesday, 16 January, so the 1st and 2nd Sundays after the Epiphany were 20 and 27 January and the double wedding was held for the children of Eucharius Schübart on Monday, 4 February.

Anna married THOMÆ, Jacob on 1 Jan 1608 in Hildburghausen, Hildburghausen, Thüringen, Germany. Jacob was born in UNKNOWN; died in DECEASED. [Group Sheet] [Family Chart]
