Have just found this forum. I've been researching the Yeates family for about 20 years now. I already know Lorraine & Bray.
Re George, William & Mrs Yeates in the Directories-
George was George Mitchell, son of Samuel, and the junior partner in Yeates & Son, Opticians (Optical instrument makers) a shop made famous by James Joyce in "Ulysses" Mr Bloom, the hero " crossed at Nassau Street corner and stood before the window of Yeates and Son, pricing the field glasses.” That was in 1904 on "Bloomsday".
I don't know who William was. The other Wms were dead by 1850.
Mrs Yeates was probably the same as Sarah Yeates in the 1842 Dir. She was probably Sarah Wilkinson, the wife of Mason Yeates, who was the son of William 1768-1834, brother of Samuel, Kendrick etc.
Lorraine has Andrew as their father , which seems OK, but I have Andrew's father as William, b. abt 1690.
William seems to have had four sons: Jonathan 1719-1778, ?John 1727, William 1728-1785 and Andrew 1735-1796.
There are so many entries in the familysearch (IGI=Mormon) index, because
Andrew's granddaughter Martha Spence went to the US and became a Mormon 'plural wife' the third of four in a polygamous marriage. She has many descendants in Utah, Arizona & other states today.
I am also descended from Kendrick through his daughter Matilda. Her baptism cert. gives her parents as Kendrick & Margaret. The IGI shows Kendrick as marrying Margaret Faulkiner on 20.4.1802, but does not say which parish.

p.s. 'Irish Genealogy Church Records' gives the date of their marriage as 28th April 1802. The parish was St. Andrew, C. of I. Dublin.
