He always makes sure to look nice, but isn't overly concerned with his clothing. He has servants trained to choose appropriate clothing for him, as he just can't be bothered. It's important he looks nice and lordly, yes, but why waste the energy when someone else can do choose his outfits with better taste than he?

687 AL & Birth: Jimeridan is born the first living child of Lord Janderian and his wife, Mirda.
689 & 2 Turns: His first sibling, a sister named Jasah, is born. Lord Janderian is pleased he has a second living child.
691 AL & 4 Turns: Another sister, Mandara, is born
693 AL & 6 Turns: Mirda finally gives birth to another son, Jimeridan's first brother.
695 AL & 8 Turns: Dondarian, a second brother, is born.
696 AL & 9 Turns: Dondarian dies of a summer illness that sweeps through the Hold. He is one of the few fatalities, too young to fight it properly. It is this event that leads to Jimeridan learning how important it is for Lord Holders to have lots of children.
697 AL & 10 Turns: His sister Mandara dies tripping down stairs. The terrible accident greatly upsets his mother, and only further reinforces the lesson of the year before.
701 AL & 14 Turns: Mirda has another stillborn child, a son. Jimeridan is old enough to understand the tragedy of it.
703 AL & 16 Turns: Jimeridan becomes an adult in the eyes of Pern, and his father gives him more responsibilities and brings him around with him to learn more actively.
704 AL & 17 Turns: Jindara is born, another sister. Jimeridan learns he really likes being a big brother. He was too close in age to Jasah to really feel like her big brother, but he does with the new sister.
705 AL & 18 Turns: His world is turned upside down when his mother dies. The healer believes something went wrong with her last pregnancy but there were no external signs of the problem. Jimeridan is devastated, but aware of his adult status and hides most of it away, paying even closer attention to working with his father and learning how to be a good Lord Holder.
707 AL & 20 Turns: Lord Janderian marries again, a women named Savilla. Jimeridan is mildly weirded out by the fact his father's new wife is two months younger than him, but understands the logic. He gets along well enough with her, as she respects his deceased mother and her children.
712 AL & 24 Turns: A match is made and Jimeridan is betrothed to one of the daughters of Lord Igen, who is almost 16.
713 AL & 25 Turns: Jimeridan and Ithola marry.
714 AL & 26 Turns: His first child, a daughter named Jorra, is born.
715 AL & 27 Turns: A second daughter, Ithara, is born.
718 AL & 30 Turns: Another daughter, Thorma, is born.
720 AL & 32 Turns: A child, another daughter, is born still. Jimeridan and Ithola mourn their first lost child.
721 AL & 34 Turns: Itherida is born.
722 AL & 35 Turns: Jira is born.
725 AL & 37 Turns: Ithola miscarries her pregnancy.
728 AL & 40 Turns: Daughter Marielle is born.
731 AL & 44 Turns: Lord Janderian dies and Jimeridan becomes the Lord of Nabol. Later in the turn, Ithola gives birth to another stillborn daughter.
732 AL & 45 Turns: Ithola dies from some sort of fading illness. Jimeridan mourns, but is in some ways relieved, because he now has to worry even more about producing an heir and Ithola was only giving him daughters.
734 AL & 47 Turns: Jimeridan marries Haleah.
735 AL & 48 Turns: Haleah gives birth to her first child, a daughter (Jala). Jimeridan is mildly dismayed, but Haleah is young still.
737 AL & 50 Turns: Another daughter, Himerah, is born.
739 AL & 52 Turns: Haleah is currently pregnant again, and Jimeridan really hopes this one is a son. His brother Maveridan is his heir, but Maveridan is 46 and Jimeridan would prefer a younger heir. Of his remaining brothers, he considers Veridian and Rinderian unsuitable, and Jazarin is wholly uninterested (though he would become heir if anything happened to Maveridan).
Month 11 - Hurrah, a son is born!
