Thanks again CaroleW,
I've just received an email confirming Arthur was Baptised on June 4th.1865 following his birth on 17th.June 1864 at St.Johns church Richmond Surrey. Mother a singlewoman Elizabeth Timmis.
Yes you are correct about Ernest . Also born to a singlewoman Elizabeth Timmis in Birmingham.
Elizabeth Timmis also had a daughter Ann born illegitimately around 1859. Elizabeth later married a William Austin and had five children with him.(Oh no, another branch of the tree ! )
Now all I have to do is find out what happened between 1867 and 1871 to change the boys names from Timmis to Robins. Adopted perhaps ?
