I found 3 baptisms all done on same day 25th October 1885
William Henry Tribe b 1885 26th May
Ada Agnes Tribe b 1880 7th July
Edith Annie Tribe b 1883 29th April :
The parents given were Wm Henry Tribe ( labour) Benhilton, All Saints, Surrey, England and mother Mary Annie Maria Hooper
This I can confirm mother of Ada Agnes birth register 1880 Epsom, she was registered as Hooper thus due to mother not officially being wed.
In 1881 Census Ada Agnes is living with her grandfather Frederick ( bricklayers labour) widower in Espom also her mother Mary and an Emily b 1874 Epsom who was Mary sister and went on to marry Alfred Brewer in 1891 Epsom.> a year after her sister weds Wm H Tribe.
The deceased mother was Maria Rowley having wed Frederick Hooper on 21 Jul 1861
Marriage Place: Ewell, St Mary, Surrey, England.
1890 13th Jan marriage of Wm H Tribe born 1861 to Mary Hooper b 1864 in ewell surrey. Wm now says he is itinerant musician, no father given and Mary Hooper gives father Fredrick Hooper labour. The one noticeable thing I see both signed names not by marks, which suggests both can read and write.
I cannot see anything that suggests from mothers side they were romany .
I did find this in 1871 Espom Wm Tribe b 1863 Espom as grandson with grandparents John b 1818 Sussex wife Martha Rapson married in 1837 Lurgashall,Sussex,England. I cannot confirm this is right Wm Tribe just thought I let you know might be worth researching.
