Hi Jessica Could be worth e mailing this society http://www.brandeis.edu/centers/wsrc/ernestinerose/highgate.html They have a lot of information about Ernestine and mention her husband a fair bit - they are both buried in Highgate Cemetery. The name spelling they are using is Ernestine L. Susmond Potowski Rose. According to another site, she married William in 1835 and her father's name was Isaac.http://www.highbeam.com/doc/1G2-2591308061.html Would be great to find a record of the marriage and that should provide more clues. Another site says they married in 1832 and another in 1836. William was born around 1813. You may be able to find baptism records for him. There's also some info in http://www.nationalarchives.gov.uk/a2a/ <both died in England - he in London, and she in Brighton Jessica Leschnikoff> Naomi Ogin Brisbane
