At this point I ask you to bear in mind that 10 years ago, neither I nor anyone else in my own Frankenstein branch knew of the existence of the family of Rachel Frankenstein, who is the central character of this part of the family story. Nor did we know of the existence of Abram Rajn's family, and how they are connected to us. The ignorance was total, and mutual.
None of us knew anything. The links which appear to have been so strong 100 years ago had grown weaker over the generations, and all but disappeared. All but: the one exception was a vestige of a family Tree reconstructed by Rajn and Boll cousins in the USA, who knew they were linked to each other by the two Frankenstein sisters, Tauba and Rywka Laja. They also knew there were more Frankenstein cousins somewhere, but they didn't know who we were, or where to find us. You can see how we found each other here: Finding more new cousins.
Since then we've got our collective heads together, rummaged through archives, searched the far corners of the internet, walked the streets, shared photos, you name it. We even have a Facebook Group with over 100 members, all Children of Frankenstein ....
Here's what we know so far. First, the dates we have are:
1905: baby Jacob
The first mention we have of the house is in March 1905, when baby Jacob is born there to Morris Lefcovitch and his wife Rachel Leah Frankenstein.
Rachel's father Israel Jacob had died in Poland some time in the mid-late 1870s, and her mother Sarah came to London a few years later with Rachel, and her siblings Boruch (Barnett) and Bajla (Betsy); Rachel's older brother Jonah (Jacob) was already there - his first child Moses was born in London in 1879. Rachel and Morris were not in this house in the 1901 Census - they were in Spelman Street, another place that figures repeatedly in the family story - so they must have moved to Underwood Street some time between that Census and the birth of baby Jacob in March 1905.
Rachel and Morris are still there in April 1911, when the next Census was taken, and we have no documents showing them anywhere else until they set off for (another) new life in Australia in January 1913.
But before they go, they play host to a couple of family events that allow us to firm up our understanding of how some of the members of our Frankenstein clan relate to each other.
1907: Abraham and Bloomah
The first occasion is the marriage of Abraham Isaac Ray and Bloomah Freedman in 1907 (see It's Rajning Cousins)
Fanny is a shadowy figure. She appears in the 1901 Census as a grand-daughter of Rachel's mother, Sarah Frankenstein. She is shown as born in Gombin, the family's home-town, around 1887, but we know little about her parents. We see on the Certificate that her father was Samuel Shalinsky, but we have found no further trace of him either in Poland or in England. As for her mother, we have to presume that she was a daughter, as yet unidentified, of Sarah and Israel Jacob. In other words, Fanny's mother is a sister of Rachel Frankenstein Lefcovitch.
