Input: Question: What profession did Daniel Ernst Jablonski's older brother have? Passage:Jablonski was born in the village of Nassenhuben, near Danzig (Gdańsk). His father, Peter Figulus, was a minister of Unity of the Brethren (; – also known as "Bohemian Brethren"); the son preferred the Bohemian surname Jablonski (Jablonský) which was based on his father's birthplace – Jablonné nad Orlicí. He was the younger brother of Johann Theodor Jablonski. His maternal grandfather, Johann Amos Comenius (d. 1670), was the last bishop of the Unity. Having studied at Frankfurt (Oder) and at Oxford, Jablonski entered upon his career as a preacher at Magdeburg in 1683, and then from 1686 to 1691 he was the head of the Brethren college at Polish Leszno (), a position which had been filled by his grandfather. Consecrated a bishop of the Unity for the churches in Poland, he was encouraged by the Elector Friedrich Wilhelm I of Brandenburg, King in Prussia, to secure the Apostolic Succession to the Renewed Unity of Brethren, the Moravian Church, and consecrated David Nitschmann bishop in Berlin in 1735.
