Hi Woozle,
Sorry I had to disappear for a while, as real life has been interfering with my genealogical pursuits. I have now looked through my files and nothing there fits with your people. I have also reviewed the posts on here and can see no obvious (or not so obvious) solution to your problem.
Before I go any further, I should point out that the second
Buckland marriage that I found, suggests that there was no
Thomas Stevenson marriage (except perhaps in the wishful thinking of who ever submitted that entry to the IGI). In the more trustworthy extracted entry, the name is Stephens, not
Stevenson. There were people named Stephens/Stevens in
nearby villages and that Thomas probably belonged to one of those families. So, I would dismiss the Buckland marriage and any connection to Standlake and concentrate on the Stimpsons/Simpsons.
The parish register entries found by Debbie indicate that the vicar or clerk did confuse Stimpson and Simpson, so perhaps
Stevenson was yet another mistake. I think it is likely that your Robert was a child of Thomas and Mary Simpson or Stimpson, born in that 10 year gap. The only problem is , how on earth do go about proving it ? A will would be nice.
You might check to see if Thomas Stimpson or Simpson did leave a will. I don't know what he did for a living, but even
small tradesmen or craftsmen sometimes made wills. It's worth looking.
I am going to send you a PM with contact details for a most helpful person, who is doing a small one-name-study of the names Stevenson, Stimpson, Stimsom, Simpson, et. al. in Berks/Oxon. I hope he can help you.
Regards,
Carmela
