Hi Richard I am interested in the Tyack family because they married into my ancestral family, the Pethericks of Camborne, Cornwall. Your ancestor, John Tyack 1838 (married Henrietta Peters Harry) was the brother of James c.1835 who married Mary Jane Petherick 1833. She was the sister of my gt gt grandfather William Petherick 1830 so although we are not related, our families are. I am also interested as your family moved into the Worcestershire/ Warwickshire area which is very near to where we used to live near Redditch.(We are now in France!)We are quite familiar with the Alcester, Pershore, Evesham areas.
