Katharina Wimmer - Are Sabine Rind (Wimmer) and Katharina Wimmer two persons or just one?

Attention, Randy Schoenberg, Private User, and Private User:

I have been working on the Rinds of Přehořov, trying to add documentation to profiles that lack it (which, to my irritation, I have found that almost all of them do, or rather did until now). Doing so has led me to this question: Are Sabina Rind and Katharina Wimmer two distinct persons or only one person under different names?

There are, so far as I am aware, only two documents pertaining to Sabina: the record of her marriage to Jakob Rind on 19 May 1844 and the record of the birth of her son Bernard Rind, which I have just discovered today. (There was no profile of such a person until now.) Until today, Joachim Rind was attributed to Sabina as her son; but I have removed this attribution, as it is contradicted by Joachim's birth record, which names Katharina as his mother. Likewise, the mother of Jakob's children Sali Arnstein, Maria Rind, and Adolf / Abraham Rind is identified as Katharina in all of their birth records.

On the hypothesis that Katharina and Sabina are two different women, the sequence of events has to be this: Katharina bears Jakob's children Joachim (1831), Sali (1833), Maria (1836), and Abraham (1839); then, at some point between 1839 and 1843, her place is taken by her sister, Sabina, who bears him her first child on 21 Oct 1843. On the 19th of the following May, she and Jakob are married.

Note that Jakob is identified as "ledig," not "verwitwet," in the record of his marriage to Sabina. In defense of the hypothesis that Katharina and Sabina are two distinct persons it could be argued that, since Jakob was never legally married to Katharina, he could have been bereft of her without thereby acquiring the status of a widower. This seems to me strained and implausible.

As far as I can see, the only reason to believe that Sabina and Katharina are two different women is that they have different given names: they have the same parents, as well as the same husband. As it was exceedingly common for women in this historical context to use different given names at different times, I do not think that this is a sufficient basis for identifying them as two different persons. I therefore propose to merge their profiles.

I have written this message, however, to test whether there are any sound objections to my doing so.
