Nathan is right on both counts.
There are two primary ways a Jew ended up Grisha.
1) A G-starting Russian name was taken or given as a civil name (usually
Georgi and Gregori), in conjuction with whatever Hebrew-Jewish name was
carried (usually this would have been a Gimel-starting name like Gershon or
Gavriel, but not necessarily). The road >from Georgi and Gregori to Grisha
needs no further explanation, and the road back to the English equivalents -
George and Gregory - is no more difficult.
2) Russian doesn't have the G sound (G as in good; they certainly have G as
in gyroscope...) so many a Hirsch (Tzvi) walked around being Grisha. (I
remember one of my trumpet teachers telling me to "drop everything else and
work on the Gaydn").
When Hirsch's entered the English-speaking world, many of them became
Harry's. Bambi could also work, but it's not as common....
1. Diminutive for Russian Georgi (Georgij) is not Grisha but Gosha,
sometimes fancy Goga or Zhora as evolved >from English George (Russian
Dzordzh). In Ukrainian Grisha is known as Hryc >from Hryhory (Gregory).
2. Russian uses hard sound "g" (as in Gorbachiov), they do not use sound
"h", hence Golivood, Gaiti, Gavana, Gonduras, Gonolulu and Gonkong.
It is Ukrainian that has no use of hard sound 'g',
