Did Omar ibn al-Khattab establish the hadd punishment on his son for consuming alcohol? And who was this son, and when was he born?

Umar ibn al-Khattab publicly flogged his son Abd al-Rahman with the Hadd punishment for drinking alcohol in Medina, and he did not consider valid Amr ibn al-Aas's secret flogging of him in Egypt. His son lived for a period after that and died from an illness, not due to the flogging. The son's date of birth is not mentioned.
