The Merit of Burial Near One's Ancestors

Is there a significance to purchasing a grave near one's ancestors' graves?

If you are on the level of righteousness as they are, there is a great merit in it. (Except for a married woman who is buried next to her husband and his family)

Gemara Makkot, page 11b: "It was taught: If one dies before the High Priest, they carry his bones to the graves of his ancestors, as it is written: 'The murderer shall return to the land of his possession.' What is the dwelling in the land of his possession? You must say: This is burial." This implies that the burial place is near his ancestors. Similarly, the Rema ruled in Siman 363, paragraph 2, that one does not move a deceased from his city to be buried in another city unless there is no grave in his city or to be buried in the graves of his ancestors. It is even permitted to move a deceased from his grave to be buried in the graves of his ancestors.
