I seem to be the first to leave a message so i hope someone else out there is researching Eggar!
My maternal grandmother was Mabel Eggar (born 1905, died 1989).
She had eight brothers and sisters - William (1905 -grandmother's twin), Katherine known as Kitty, Sarah known as Dolly (1896), Nellie (1899), George(1892), Charles, Alfred (1890) and a baby that died in infancy.
Their parents were Alfred Eggar (born 1867)and Elizabeth Martha Goodall(born 1871).
Alfred's brothers and sisters were Charlotte (1850), George (1856), James (1859), William (1854), Charles (1865) Stephen (1863), and Kate(1869).
His parents were George Eggar (about 1815) and Sarah(about 1829).
Are any of these names in your tree. Please contact me if so as i have some information to share and lots of family photographs.
