Moshe Chaim, Czar of Pinsk: #14 Dora and Ockham's Razor

The story so far
Dora Zaturensky was the sister - or half-sister, maybe - of my great-grandmother Shprintsa. Their father Movsha may have had 2 wives; Shprintsa was born in 1858, and may have been the daughter of the first wife, and Dora, b 1869, the daughter of the second.

I have identified DNA matches with 2 of Dora's great-grandchildren, Cousin Paul and Cousin David. David is a descendant of Dora's first husband, Gitelman (we don't know his given name), whilst Paul is from her second husband, Jacob Kawin.



The paper trail says I have exactly the same relationship to both Paul and David: half-3rd Cousin. So why is there such a huge difference between the amounts of DNA I share with them? Or, to ask the question another way around: why do I share so much more DNA with a Kawin descendant than I do with a Gitelman one?

I've had a question like this before, in this same family. In that case, it seemed the solution was that there was probably a double relationship somewhere along the line - that Movsha's son Shmuel had married his cousin Rochel Leah, for instance. Is something similar happening here?

For this to be the case, I would have to have a single relationship with David, via Dora, and a double relationship with Paul. This second relationship could occur at any point in the Tree I have researched so far - via Paul's father's family (which I think is most unlikely, having had a quick look at his ancestry), that of his maternal grandmother Alice Cowan (wife of Sam Kawin), which also seems unlikely, or through Jacob Kawin himself. And the implication of this is that Jacob and Dora would have to be be fairly close cousins.

In other words, one of Dora's parents would have to be a sibling to one of Joseph's: either Dora's mother ('2nd wife' in the Tree above) would be a Kawin, ie a sister to Joseph's father Max, or Joseph's mother would be a Zaturensky, a sister to Dora's father Movsha. We don't have any information on Dora's mother, but we do have several references to Joseph's mother as 'Hinda Sandusky'. It is possible that this could be a variant on 'Zaturensky', but the Sandusky name does occur in several places, and in any case it's not a very convincing rendition of Zaturensky. At the moment I'm tending towards Dora's mother being the connection.

A tantalising Tree
Then I came across this tantalising clip from a Tree on the JewishGen 'Family Tree of the Jewish People' (log in required). It was posted nearly 20 years ago, at a time when it was not possible to do much online research, so I'm assuming it's the product of family knowledge, and possibly some archival research in Belarus. I've written to the person who posted it, asking where the information comes from; fingers crossed I'll get a response!


The layout is not 100% clear, but it seems to be saying that Benjamin is the son of a Mosha Lipschitz from Pinsk, who died in 1886, the same year as Benjamin was born. The mother is unknown, but she is not Dora, who seems to be Mosha's second wife. The dates given here suggest Dora must have married at the age of 14, though we have her down elsewhere as born in 1869, which would make her 17 at the time of this marriage.

In addition, if Benjamin is the son not of Dora but of an earlier wife, this first wife would need to be closely related to Dora - preferably a sister - so as to retain my DNA relationship with David (see my draft Tree above).

Fact or fancy?
All this suggests the following scenario:

1 Mosha Lipschitz and first wife have child Benjamin in Nov 1886
2 maybe first wife dies in childbirth or shortly after
3 Mosha remarries immediately, to Dora
4 Mosha himself dies
5 Dora packs her bags and goes off to Peoria to marry Jacob Kawin, leaving her stepson Benjamin behind

- all in a matter of weeks.

Oh dear. There's too much going on here, and it's putting a tremendous weight on Dora's 17-year old shoulders. I'm not happy with it.

Ockham's Razor
At this point I am reminded of the wise words of the medieval philosopher William of Ockham, who is reputed to have argued along the lines of "Don't make an explanation more complicated than it needs to be", or, as expressed by Bertrand Russell, "always opt for an explanation in terms of the fewest possible causes".

So what can we identify as the "fewest possible causes" in this case? Looking at our suggested scenario again, the only things we can take as fact are:

1 Benjamin was born around 1886, probably in Pinsk
and
5 Dora went to the US around 1887, probably from Pinsk

Plus,
6 We have seen that Benjamin brought his own family from Pinsk to Peoria in 1922, and lived for 20 years or so in a house built in Dora's back yard
7 I have the DNA relationship with David and Paul outlined above

Do we really need 2, 3 and 4 to explain 6 and 7?

A closer shave
What happens if we apply Ockham's Razor to this scenario, and shave off the bits we don't need? How about discarding the marriage between Dora and Mosha Lipshits shown in the Tree above? We have no evidence for it, or reference to it, other than this Tree, and this Tree shows no sources, and could be wrong.

The consequences for Dora's story would be:
2 Mosha's wife does not need to die at this point
3 Mosha does not need to remarry, so he does not marry Dora
4 we no longer need to 'free' Dora from the marriage to Mosha, nor do we need to posit his death at this point

That feels better.

Wanted: a sister for Dora
In fact, it feels much better. Applying the razor leaves both of our outstanding queries untouched. Point 6 - Benjamin coming to live next door to Dora in Peoria, and point 7 - my DNA matches with Paul and David, are covered by just one assumption: that Benjamin's mother is indeed a sister of Dora.

This implies that when Benjamin emigrates to Peoria, he is going to live close by his Aunt and Cousins. We know he took on their surname, Kawin, shortly after arriving in the US. And it would not affect my DNA relationship with David. Our Common Ancestor would still be my great-great-grandfather Movsha Zaturensky.

The only problem is, we don't have an eligible sister for Dora.
