Hello again,
Since mailing you, I had a look at William Perkins of Tardebigge. I am assuming you know all this, but starting from the 1871 Census, he has quite a chequered history. In 1871, he is living as a lodger in the High Street, Bromsgrove, aged 69 and a Horse Trainer ( no wife and no family with him).
In the 1861 Census, he is a Groom at Moundsley Hall, King's Norton, aged 59 (again no family with him)
In the 1851 Census, he is living at the Strand in Bromsgrove, a Servant aged 49, with his young wife Ann, aged 27, and son William aged 2 and 1 year old daughter Anna M. Perkins (Maria perhaps? - Anna Maria was a popular girl's name in England even in the Edwards family linked to the Perkins in my wife's paternal family history)
But I can find no further trace of your William in the 1841 Census nor can I find a birth for a William Perkins at Tardebigge in or around 1802. I tried mis-spelling the name as I have found this sometimes comes up with the answer, but Parkins/Parsons/etc proved fruitless. There was a William Sarsons born in Tardebigge in 1806 but he's not your ancestor. And where did wife Ann and children William and Anna Maria(?) disappear to between 1851 and 1861? Happy hunting! No one said it was easy!
Regards,
Bill.
