Timing of Purim Seudah

Question

I know that typically the Purim Seudah is held after davening mincha except on Friday when it is preferably started before midday. I also know that some (if not all) Sephardim have two seudahs. I seem to recall hearing or reading that there are some opinions that the Purim Seudah should be held earlier even when Purim is NOT on Friday. Is anyone aware of what sources have this opinion and does anyone actually do this in practice or know someone who does?

Answer 1

The Terumas Hadshen
https://www.sefaria.org/Terumat_HaDeshen%2C_Part_I.110?lang=bi in the last sentence

אף כי ישבתי מנהג זה מ"מ רבותי ואני אחריהם נהגינן עיקר הסעודה בשחרית כמדומה שכן נהגו ברינו"ס: Although I have justified this custom, still, my mentors customarily eat the essential ‎meal in the morning, as do I, and it appears that this is the practice in the Rhineland.‎

Seferia

This custom of beginning the seudah in the morning is futher brought down by the Shelah: https://www.sefaria.org/Shenei_Luchot_HaBerit%2C_Aseret_HaDibrot%2C_Megillah%2C_Ner_Mitzva.11?lang=bi&with=all&lang2=he

וכל מי שמקדים ומזרז ביותר לעשות הסעודה בהשכמה הוא משובח בעיני וכן כתב מהר"ר איסרל"ן שהוא ורבותיו נהגו בכל השנים עיקר סעודה שחרית וטעמא דמסתבר הוא דהא זו הסעודה היא נגד סעודת אסתר שעשתה על המלך ובודאי היתה הסעודה בעת שדרכן של המלכים לאכול ובסעודה זו Whoever has an early Seudah is praiseworthy and he quotes the above Terumas Hadshen.

The Elya Rabbah has a similar view

The Mishna Berura here:
https://www.sefaria.org/Mishnah_Berurah.695.9?lang=bi&with=all&lang2=en

This does not mean one should make his seudah only in the morning, but to avoid beginning at night when it is after purim. So there are those who make the Seudah in the morning.
