Lewis Bonson Yates was my Gt Grandfather. This is a very complex family as there are a number of name changes.
Jane Yates: 1840 - 1909
Parents - John Yates 1809 - 1840 & Ann Davis 1811 - 1889 (m: 1837)
Siblings - John Henry James 1832 - 1872 & Ann 1835 - 1887
When John dies Ann then marries John Cottee 1795 - 1870 in 1842 (both listed as widow/ers on certificate)
In the 1841 census Ann & John are living next door to each other in Ash, Surrey.
Jane has child Lewis Bonson Yates 1858 - 1939 - no father listed on birth certificate. On his baptism he is listed as Lewis Bosson Cottee
In 1860 she then marries Richard Stallwood 1835 - 1876. They have 7 children:
Emma Jane
Richard
Beatrice Alexandra
Ernest
Ruth
Owen
Lydia
She then remarries after Richard' death in 1882 to Daniel Owen Teasdale 1838 - 1909. They have one child:
Daniel
Lewis Bonson Yates is listed as Stallwood whilst living with Jane & Richard. In 1879 as Yates he marries Lydia Wood 1856 - 1915. They have 13 children:
Florence Ruth
Lewis William
Edmund
Arthur Richard Bonson
Gertrude Ellen
Ernest Edward
Harry
Christina Maud
Frederick John
Margaret Annie
Walter Leonard
Alfred David (my grandfather)
Lydia Frances
He appears on 1881 census as Yates & then uses Stallwood on 1891, 1901 & 1911. All of his children were registered on Birth & Marriage certificates as Yates.
Hope this is of help, it's taken quite a while to get this far

If anybody has anything else, would be great as I'm finding out information as I dig deeper.
