Ann Norris (Hynson) - Connections

I'm tracing a cousin line and got to my ancestor Ann (Hynson) Norris and see that on the Geni pathway I'm tracing, her mother and her mother's sister show as:

Anna Hynson (Letchworth) her mother → Ann Anna Hynson (Letchworth) her sister

I think it's unlikely my ancestor Anna (Letchworth) Hynson had a sister by the same name who also married a Hynson.

but I also see that my mother of my Ann Hynson, while showing Letchworth as her maiden name, has her as:Daughter of Edward Powell and Elizabeth Powell (Costerdyne), which would mean she's a Powell and not a Letchworth.

Her FInd-a-Grave doesn't list parents for her but people have Ancestry trees connecting the Powell parents to her but still referring to her maiden name as Letchworth.

Given that there is a sister connected to Anna (Letchworth) Hynson who was apparently a Letchworth by birth, I think maybe the two women have become confused and that my ancestor is the one who probably wasn't actually a Letchworth.

At the moment I have too many tabs open on my laptop to open any additional tabs until I've worked through and closed some, which won't happen tonight. So I'm just shining a light on the same-name sisters and my belief that my line might not be connected correctly. I can't even add the other profile links since I can't open any additional tabs at this time.

Thanks in advance if anyone has time and inclination to check the same name 'Letchworth' sisters.
