I have family from Egloskerry that started there in the early 1700s and I have conducted extensive research into that parish. By now you may have gotten the information you needed about Stephen Hoskyn of Egloskerry. If not, here is what I was able to find from thr OPC database...
Stephen Hoskyne, son of Stephen, buried October 26, 1681.
Thomasin Hoskin, wife of Stephen, buried February 6, 1689.
After the death of Thomasin, Stephen likely remarried (although no marriage of it was recorded in Egloskerry) because...
Thomasine Hoskin, infant daughter of Stephen, buried December 26, 1695.
Stephen Hoskin, infant son of Stephen, buried January 7, 1699.
There is no christening record for either of these two infants in Egloskerry, which may indicate that either they died prior to being christened (at a few days old) or that they were christened in another parish (less likely).
Hoskins continued living in Egloskerry through the various censuses of the 19th century. Hope this helps. Would like to hear your "story" of the Hoskin family.
