There was another kinsman with a closer claim to her
We know very little of Kilion (Ruth's husband) from the narrative and certainly not enough to know if he and Boaz were close friends. However, since Boaz was very familiar with Naomi, Kilion's father, it stands to reason that they were probably friendly, but there is no certainty in this.
Obed is the only son of Ruth and Boaz, it is in Ruth chapter4.
Ruth 3:7 And after Boaz had eaten and drunk, and his heart was cheerful, he went to lie down at the end of the heap of grain; and she came softly, uncovered his feet, and lay down. This may seem very irregular to us in our culture, but actually it was the accepted practice in that day and there was nothing evil or suggestive about it.
Fom the line of Ruth and Boaz.
Ruth Harkness is known for bringing the first giant panda back to the United States. It is not known if she had any children. Her husband was Bill Harkness.
Boaz
No. Tradition states that Boaz died shortly after marrying Ruth, and they had a single son. See also:More about Ruth
The rising action in the book of Ruth includes Ruth's decision to stay with Naomi, Ruth's gleaning in Boaz's field, Naomi's plan for Ruth to approach Boaz, and the development of Ruth and Boaz's relationship. These events set the stage for the climax of the story.
Boaz (Ruth 4:13)
Boaz died after he married Ruth, and had a child as well but when he died the bible does not say.
Yes Ruth and Boaz were related to Jesus.Ruth is the great, great grandmother of David.
Rahab was the mother of Boaz by Salmon, Boaz had Ruth as his wife and begat Obed. Although this is stated as such in the NIV, the KJV is much clearer. The record is seen also in Ruth, regarding her marriage to Boaz and having son Obed. Rahab, the harlot, was in the ancestry of Boaz, of David and of Jesus Christ. This was because she turned to believe in the true God of Israel, while the rest of her city rejected Him.
