The same name is mentioned in the Book of Samuel. This Amminadab was an Israelite mentioned in the lineage of Jacob's sons, Exodus 6:14-28. Mathew 1:1-16 shows a full record of ancestors and descendants. He likely served in the tabernacle. He was one of 112 Levites who received the great honor of bringing the Ark of the Covenant, back to Jerusalem from the Philistines.
According to the Biblical genealogies, he was a son of Ram (also known as Aram).  He was born during the Israelite exile in Ancient Egypt. Ram was the great-grandson of Judah. Amminadab was the father of Nahshon, chief of the tribe of Judah (Numbers 1:7; 2:3; 7:12, 17; 10:14). His daughter Elisheva was Aaron's wife (Exodus 6:23), making him Aaron's father-in-law.
Amminadab is one of the ancestors of Jesus painted in the lunettes of the Sistine chapel.
