Sorry, Dennis, but we don't know exactly when Jacob Fränkel (son of Leibish Frankl & Rifka Turteltaub) was born. All we know exactly is that his brother Israel was born on 26 April 1849 & we don't know the dates of the other brothers & sisters.
If you haven't tried that, you might want to look at it. It's wonderful, but limited. Good luck with Jacob. You may need it because there must have been many hundreds, if not thousands, of Jacob Frankel's in Eastern Europe in the 19th century.
Incidentally, you may have the present country of the city Lissa reversed. Up until 1945 Lissa was in Germany, at least it was during WorldWar II. Since 1945 it has been the city of Leszno in Poland. Of course, in the 19th century with all the changing borders you'd have to look at a 19th century map to determine what country it was in then.Good luck.
