Big Mac, Cheerilee, Apple Bumpkin, Berry Belle, and Apple Barrel.
Big Mac had started dating Cheerilee after the love potion incident and while they had their ons and offs he eventually married Cheerilee and they settled down on a small section of Sweet Apple Acres. They soon had their first child, Berry Belle. The filly was a handful, adventurous as Applebloom had been, but thankfully her parents knew how to deal with such things. As she grew she instinctively took to teaching, helping her classmates learn and grow just as her mother had. The second child to Big Mac and Cheerilee, Apple Bumpkin, turned out just as big as his father with an impressive set authoritative skills. If the farm didn’t need him he probably would have gone off to the guard and been commander in less than three years, but the farm called more than the guard and so he stayed home to help out. He’s as strong as Big Mac, and it’s put well to use. Third born, Apple Barrel, turned out to be extremely intelligent. First in her class to get her cutie mark, and deeply interested in mathematics. She took on the task of handling the farm’s accounts, causing the family’s fortunes to soar since. Far from being an office only worker, it’s not uncommon to see her out in the fields with her family when harvest season comes along. She’s not sure how the family managed to keep the farm going when there was only three ponies strong enough to work but with the ever growing clan living at Sweet Apples it’s steadily becoming one of the largest farms in Equestria and the Apple family, once known only for it’s size, has rise to the ranks of nobility thanks AJ being a bearer of harmony and personal friend of all four princesses.
