I can only start the tree with Joseph Willmington (Willmonton, Woolimonton - the spelling seems to vary - in Australia in Queensland it has also become Wilmington & Willmington) Don't know who Mrs Joseph was but they had a son William born on 14th july 1773 in Yeovil, Somerset, England. He married Martha Collins and died in Yeovil on the 16th June, 1825. They were glove manufacturers. They had the following children. William, Mary, Elizabeth, Henry, Amelia Collins, Emma Matlida, Sophia Collins, Phillip Collins, Edwin Collins,Mary Anne Collins.Their son, William, christened on the 19th June, 1798, married Sarah Shorland on the 20th September 1822 and died on the 12th July, 1870 at Drayton, Queensland. Sarah was the daughter of Dr. Thomas Shorland. They and their children migrated to Australia in 1842. Their progeny were:-
