Below is the apparent source of John William Helsdon (b. 1568). However, even if his wife was named Margaret, she would be far younger than the Margaret (b. ca. 1544) who married Cuthbert Elsden in 1563. Therefore, I am cutting the marriage connection between this Margaret Unknown (b. ca. 1544) and John William Helsdon.
I suspect that this is actually two different men (brothers), sons of Christopher (Elsden-10). Whether John Heilsdon or William Heilsdon married someone named Margaret is uncertain, but I suspect it was William.
