That chart is not going to help anyone in their walk with Christ; and the Bible is its own problem, for it is not trustworthy, and cannot pass simple tests.
It doesn't say son-in-law; it says "son" -- there are words for "son-in-law". What other proof do you have that Miriam was born of Heli? Every fact must be established in the mouths of two or three witnesses.
apparently you are having an issue believing God's Word.
i recommend studying the family tree of John the baptist. John's mother Elizabeth and Mary were cousins, through the Priest line (for Mary this was on her maternal side - Mary & Elizabeth's mothers were sisters).
Luke 1
There was in the days of Herod, the king of Judaea,
a certain priest named Zacharias,
of the course of Abia: and his wife was of the daughters of Aaron, and her name was Elisabeth.
6And they were both righteous before God, walking in all the commandments and ordinances of the Lord blameless.
7And they had no child, because that Elisabeth was barren, and they both were
now well stricken in years.
8And it came to pass, that while he executed the priest's office before God in the order of his course,
9According to the custom of the priest's office, his lot was to burn incense when he went into the temple of the Lord.
10And the whole multitude of the people were praying without at the time of incense.
11And there appeared unto him an angel of the Lord standing on the right side of the altar of incense.
12And when Zacharias saw
him, he was troubled, and fear fell upon him.
13But the angel said unto him, Fear not, Zacharias: for thy prayer is heard; and thy wife Elisabeth shall bear thee a son, and thou shalt call his name John.
14And thou shalt have joy and gladness; and many shall rejoice at his birth.
15For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother's womb.
16And many of the children of Israel shall he turn to the Lord their God.
17And he shall go before him in the spirit and power of Elias, to turn the hearts of the fathers to the children, and the disobedient to the wisdom of the just; to make ready a people prepared for the Lord.
18And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.
19And the angel answering said unto him, I am Gabriel, that stand in the presence of God; and am sent to speak unto thee, and to shew thee these glad tidings.
20And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season.
21And the people waited for Zacharias, and marvelled that he tarried so long in the temple.
22And when he came out, he could not speak unto them: and they perceived that he had seen a vision in the temple: for he beckoned unto them, and remained speechless.
23And it came to pass, that, as soon as the days of his ministration were accomplished, he departed to his own house.
24And after those days his wife Elisabeth conceived, and hid herself five months, saying,
25Thus hath the Lord dealt with me in the days wherein he looked on
me, to take away my reproach among men.
26And in the sixth month the angel Gabriel was sent from God unto a city of Galilee, named Nazareth, 27To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin's name was Mary. 28And the angel came in unto her, and said, Hail,
thou that art highly favoured, the Lord
is with thee: blessed
art thou among women.
29And when she saw
him, she was troubled at his saying, and cast in her mind what manner of salutation this should be.
30And the angel said unto her,
Fear not, Mary: for thou hast found favour with God. 31And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. 32He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: 33And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
34Then said Mary unto the angel, How shall this be, seeing I know not a man?
35And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.
36And, behold, thy cousin Elisabeth, she hath also conceived a son in her old age: and this is the sixth month with her, who was called barren. 37For with God nothing shall be impossible.
38And Mary said, Behold the handmaid of the Lord; be it unto me according to thy word. And the angel departed from her.
39And Mary arose in those days, and went into the hill country with haste, into a city of Juda;
40And entered into the house of Zacharias, and saluted Elisabeth.
41And it came to pass, that, when Elisabeth heard the salutation of Mary, the babe leaped in her womb; and Elisabeth was filled with the Holy Ghost:
42And she spake out with a loud voice, and said, Blessed
art thou among women, and blessed
is the fruit of thy womb.
43And whence
is this to me, that the mother of my Lord should come to me?
44For, lo, as soon as the voice of thy salutation sounded in mine ears, the babe leaped in my womb for joy.
45And blessed
is she that believed: for there shall be a performance of those things which were told her from the Lord.
~
and bring forth a son, and shalt call his name JESUS. 32He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David:
David was not the actual father of Jesus, yet is called so, having descended from him.
