Is Jacob or Heli the grandfather of Jesus Christ

It is very hard to trace back again in our time Apostle Paul said in 1 Timothy 1:14 that we cannot trace back the genealogy of Mary, there is no record of Lineage of Mary but there is possibility. Apostle Paul said told us that Jesus Christ came from Judah, if Judah is not Jesus Christ grandfather then there is possibility that Heli is his grandfather and we should not question the authority of the Bible Apostle Paul said Jesus Christ is from Judah, that is Apostle Paul's problem, not mine
