She was tentatively identified as the wife of Thomas Brownell the immigrant to Portsmouth RI. This identification seriously needs to be revisited by a competent genealogist. If this Anne Bourne is Mrs. Brownell, then she was 96 years older than her daughter Anne Brownell Wilbor's last child born in 1703, and Anne Wilbor was not even her youngest child. This account seems to be universally accepted, but I do not find a 49 year old mother followed by a 48 year old mother to be credible. I see the age of 47 to be the general cut off age for mothers of those times. At least for cases that are indisputably documented, anyway.
