Pineapples are fruits that are indigenous to Jamaica -- they occur naturally.
I don't know why there are 5 of them - maybe the artist who conceived the coat of arms thought 5 looked pleasing.

Yeah.

I wrote this a while back to answer the same question.

Genealogically it is a man, a woman, and their child(ren). In real life it may be different. The most extreme example I can dream up is two casual acquaintances, Frankie and Johnny. He treats her wrong, she reciprocates. They get snockered one night, couple without protection, and produce a child, Angela. They live together for a year, bickering constantly and slapping Angela when she whimpers. They break up when Johnny goes away to do twenty years in a federal pen. Frankie seeks pharmaceutical consolation. She scores some heroin twice as strong as she expects it to be and dies with a smile on her face.

Angela is a problem child. She gets adopted by a same-sex couple. They already have a Bosnian orphan, Boris, and Mike, a child from Northern Ireland whose unmarried Catholic mother gave him up for adoption because his father was a Protestant. The five of them grow tomatoes in the back yard. They read together; Dr. Seuss, then Beverly Cleary, Harry Potter and Voyage of the Basset.

SSC Adult #1, Pat, teaches the kids to ride a two-wheeler and hit an outside curve. SSC Adult #2, Sandy, lets them help in the kitchen, even though they make a mess and it takes longer. They let the dinner dishes soak while they talk about things around the kitchen table. Pat and Sandy are there when Angela breaks her arm falling out of the apple tree, gets first place in the three-legged race at the church picnic, falls in love for the first time and gets accepted to Stanford.

Boris becomes a mechanical engineer. Mike, after a stint in the Air Force, flies for United Airlines. Angela, since her hands are small, goes into pediatric surgery. She fixes hearts the size of a walnut for a living. Every year they come home to Pat and Sandy, who are older and greyer now. The first night of the week, every year, they go into the back yard, join hands around the apple tree, and thank the Lord that there is more to "family" than whose loins you sprang from.

Genealogy websites are no use in finding 'relations' which suggest living people and regardless of what TV adverts sell you ancestry.com is not how you research, especially in Germany, you would be getter off using familysearch ( which is free) but ONLY for dead ancestors.......... living people you need to look at telephone directories..and no you will not get German citizenship, unless one of your parents was a citizen when you were born

Obviously, your grandmother is a descendant of Rabbi Levi Yitzchok, or the fact that only descendants have this surname is incorrect. Those are the only explanations as to why she can have it as a maiden name. It's actually well within reason she's a descendant given that she's from Zhytomyr, which contains Berdichev in it. Other than that, there is nothing more I can add to the discussion.

If you are asking about her connection to the Rabbi, that's above; however, I guess her connection to the other people of the website is that she's of a group that they're interested in. If there is a deeper connection, no one here can possibly know that, nor know much more about your family unless we have access to some nifty geneology websites. Giving us names of people we likely don't know isn't that much of a help, and really you should rely on family lore to figure this stuff out, not people on the Israel forum.

It isn't in the surname origins book I favor.

(Free) has 2,426 records for it. By comparison they have over 150,000 for "Pack", which I know from personal experience is uncommon, and over 28,000,000 for "Smith". So, it is VERY rare. Most of the records are in the USA, which hints, but does not prove, that the immigrants changed it from something else. Here are the top 10 collections, ranked by number of records:

West Virginia Births, 1853-1930 223 results

One of those records may have your great grandfather. Only research will tell you where he came from.
