My theory on the baby goes this way

The baby is Ace's. Yes the blood line of the great pirate king is still alive. When Ace was on the hunt for Blackbeard he might have come across a town where he took little rest. With the good looks that Ace had i am sure that some girl might have told him her feelings. Awwwwwwww. and later Ace experienced the life of a normal teenager for the first time and had good time with that girl. i dont know who that girl might be abd no guess on it eathir. later ace might have realized that he has to fullyfill his duty first as a Whitebeard commander and left the girl promicing that he will be back. But the fate of Ace that Oda wrote was terrible. the girl might be in pain and prebobbly cought sickness so she decided that she will first deliver the baby to somewhere safe. she remember that ace talked her about how he and luffy were brought up in Windmill village by some bandits. So she used he remaning life to deliver the last of Ace to Dadan family. Dadan refused to take care of the baby becasue she think she cant handle one more monster so Makino steps in and take the responsiblity. and there you have it a happy ending to a grave sitution.

that is my opinion but i know that you have better ideas then this so feel free to comment
