Holgate Annie Bradford Y. 9b 226
Rodo Benedetto Bradford, Y. 9b 226
TOMASSO Agnes Bradford, Y. 9b 226

It shows her surname as Tomasso and Capaldi. She might have had married a Tomasso first, or used her mothers maiden name for some reason??

I would look at her birth being more near 1885, as she would have been only 12 years old at the time of this marriage!

Use the details above and go to the gro website and order the marriage certificate. This will tell you her Fathers name.
