Did you know Martha’s Vineyard had a large deaf population as early as the 17th century and into the 20th? I didn’t, which is why I picked up this book. It describes the hereditary deafness in this community, which likely came from marriages that shared a common ancestor with this very specific, recessive gene. Small island!
The best part about this book is that it describes a community where all hearing members learned sign language as soon as they learned a spoken language, and it was incorporated into daily life with ease. Groce interviews older islanders, who are the only ones left who remember how integrated the community once was. She describes the whole community’s comfort with both languages and how they code-switched often. Even decades later, when the younger population no longer spoke sign language, older members would still find themselves signing while speaking. The unfortunate thing about this book (and Groce’s research) is that it was done so late that the entirety of the island’s deaf population had died. Though the population was big in the beginning of the 20th century (and earlier), the decline of the whaling industry and the popularity of mainland schools for deaf children led to more off-island marriages, which meant fewer marriages with a common ancestor who had that recessive gene.
The last deaf person on the island died in the ‘50s. Groce wrote this book in 1985. In fact, she mostly speaks with hearing people who *knew* members of the deaf population. If you wanted to write this book today, you couldn’t. Groce says that half of her sources had died by the publication of this book (she began research 6 years prior to publishing). It’s a shame that the account isn’t firsthand from deaf people, but apparently there is little research about this community, so I guess it’s better than nothing. Also because it was written in 1985, there’s a bunch of outdated terminology. I wouldn’t recommend reading it because it really was a lot of research. GOOD RESEARCH, but dense and more information about the Puritans than I ever want to read again. Anyways, it’s a really cool bit of history! And now you know!
