Crests of the Polish Nobility by Slawomir Gorzynski & Jerzy Kochanowski,  illustrated by Adam Jonca, Warsaw 1992, University of Warsaw Publishing and Alfa Publishing, pages 43-44. 

In a red field, three gold crosses extend to the three corners of a triangle their bases ending on a gold ring. On the coat-of-arms, in the crown over the helmet, are five ostrich feathers. 
From the Brodzic clan, the following mediaeval seals are known: 1444 Jan Dambrowka, decreed doctor; 1501 Paul of Zakliczow, canon of Plock. (F. Piekosinski, Polish Heraldry..., p. 31, 412).

The first known registration appeared in the year 1414  (W. Semkowicz, Nobility Reference..., nr 24). 

A likeness of the Brodzic coat-of-arms can be found on baptismal fonts from the end of the 15th century in churchs under the call of The Divine Mothers and Saint Katherine in Jasionow.  (J. Kuczynska, Mediaeval Fonts ..., p. 88, nr. 248). 

The coat-of-arms can be found in the later edition of Coats of Arms by Dlugoszow. 
Most widely spread in Mazowsze and Greater Poland.

Borodzic(cz), Brodzicz, Brodzicki, Brzezinski nob., Dybowski, Fra(on)ckiewicz-Radziminski,

(n.b.: the letters appearing in parenthese are possible spelling variations to
replace the letter just prior to each.)

In a red field are three gold crosses, arranged such that one points straight down, the two others up forming the sides of a triangle, all their ends meeting in the center. In that however lies variations, that some of these coats-of-arms use as follows, that a circle appears in the center, where the crosses meet, and a sky-blue field, while others do not have this circle. 

On the helmet are three ostrich feathers, on some five appear. Sometime through this circle a ring was to be understood, so many that our Duchy of Petrasancta (Saintpeter) cap. 63 always wants to have such circles as rings ex usu Fecialium, and recalls that in Swabia, Austria and around the Rhine efforts were made to find such family which bore the rings in the clan; evidently (here I am stating his opinion ) the rings were acquired in those days when men would strive in a glorious competition for a ring which was bestowed upon him who won.

With all that, that author has none among the various coats of arms like those of Brodzic, only in fol. 48 he has one with one such cross, elongated and extended in the extremities, of gold, on a circle of vigorous color: he adds that this was the arms of Cadwallader, last King of Britain. The same author writes in that same work on the merits of this cross, and I refer those interested to him.

Writing by the time of Paprocki's Home folio 89. About Coats-of-Arms folio 269. Okolski vol.. 1. folio 79. Book of Clans folio 42. MS. P. Rutka. 

Paprocki ascribes the origin of these arms to this occasion, to which they all bear witness. Kazimierz the Monk, King of Poland, was waging war against the tyrant Mieclaw and the Jadzwings associated with him, when one plucky young Pole displayed his courage to him on all occasions, protecting his side, for which he was given numerous properties in Mazovia and granted this coat of arms. Rev, Rutka designates 1038 as the year of this origin, and says that the man had a long and handsome beard, and he and the arms were named Brodzic [from broda = "beard" in Polish]. But others derive the origin of this name from the name of his estates at Brody. Paprocki recalls that he saw on the list of founders of a Plock church in 1106 three brothers, born counts of Brody, Wzebor, Swentoslaw, and Krystyn, who bequeathed a tithe from their estates to that church. There is furthermore a small town in the Plock district called Plodsko, at one time a village near which the Brodzices had numerous estates.

The governor of Multanski wrote, that one hundred thousand Turks were thoroughly defeated by Stefan, in memory of which victory, three crosses of stone were erected. The length of this family is well documented, as in Genus Polonicum providumet in Masovia propogatum. 

In the year 1422, Sieciech of Brodzic, sheriff of Lubel, signed an alliance between Wladyslaw King of Poland and the Teutonic Knights Cod. Dipl. Vol. IV. folio 114. -Krasicki's Annotations.
