My great grandfather, William Claude Theadore Arthey (b. 1889, Colchester, Essex) is listed, or assumed to be the son of Zachariah Arthey (b. c1850, Abberton, Essex) and Barbara (b. c1848, Groton, Suffolk) son, however, he is 16 and 17 years younger than his sisters Elizabeth (b. 1870) and Maude (b. 1872). I am wondering who is listed as his mother on his birth certificate.
The 1871 Census, lists Elizabeth as 'Elizabeth M. A. M. Thicker' but is subsequently listed as 'Elizabeth Arthey'.
I would also like to expand William's branch further. Based on ages and birthplaces, Zachariah's father may be Joseph Arthey (b.1811, Langenhoe, Essex) and his brother, James Arthey (b. 1847, Abberton, Essex). I am not sure the name of Zachariah's mother, but I believe his father remarried Emma, mother of James Radford.
Aside from her approximate birth year, and her birth place, I have no other information for Barbara.
