When Jade-Snow Carroll and Dulcinea Sheffer teamed up with their mother, Stella DeLuca, last year to start an organic bedding company, they called it Sister Moons. In addition to the female siblings and nocturnal references, the name was inspired by the moon’s intimate relationship with earth, how it affects the tides and cycles of nature and, subtly, our bodies. The poetry of this bond struck a nerve.

After all, there is an unmistakable attraction between the members of this narrow-minded family who seem to do almost everything together. Many of them even share a multigenerational home on a converted farm in Egremont, Massachusetts, on 15 acres of land in the foothills of the Berkshire Mountains. Ms. Carroll, 42, and her husband, Ian Rasch, 44, a contractor and contractor, live with their 6-year-old daughter in the estate’s farmhouse, which was built from 1850 to 1875 near the top of what is known as Baldwin Hill. The adjoining barn from the 1820s has been converted into two apartments, the upper one for Ms. DeLuca, 63, and the lower one for Mr. Rasch’s mother Julia Rasch, 73, who is a midwife.

Ms. Sheffer, 40, lives with her family in New Marlborough, Massachusetts 25 minutes away, but she is often encountered at the Baldwin Hill residence, which also serves as the headquarters of Sister Moons. And when her two children, 7 and 3 years old, are out of school, she often brings them with her. Like most things in this family, childcare is shared.
