European place name changes, how to find relatives place of birth

[PeggySueOooOo]

Google has failed me so I am hoping someone here will be able to advise me.

My great grandmother was born in 1892. I have her place of birth recorded in two places, one is Sashkev, Russia (1921 census) and the other is Saschkew, Russia (boat records when she emigrated in 1902).

I believe this location is in Ukraine (her father was born in Kyev). But I can't find any records of such a place ever existing. I have tried looking at some 1900 maps of Russia online but none have been detailed enough.

Any ideas?

Could Sochaczew in Poland, Sasivka (Caсiвка) in southwestern Ukraine, or Sasiv (Caciв) east-northeast of Lviv be possibilities?

Which port is on the records you consulted?

There are several places within Russia with a similar name (going by google maps when searching), the spelling will have most probably been completed by a none Russian speaking person and your ancestor will have had an accent?

Seshcha
Сеща

is nearer to Ukraine than some of the other possibilities

Sevsk
Севск

another possible?

Shatsk
Шацк

another possibility?

Sheksna
Шексна

It's the Russian equivalent of something like MyHeritage or Ancestry.

If you can read and write Russian then this is a very useful resource.

Thank you very much everybody for all of your help.

The departure of the ship she travelled from was Hamburg.
Her older brother (born 1881 so quite a but older) was born in Kiev which also made me think Ukraine, however as they all ended up in the UK they may have moved around a fair bit in the meantime.
According to my father, his grandmother never lost her accent and I have assumed that her British born husband completed the 1921 census information. The ship passenger list is not in English and actually has the place name split across 2 lines Sasch Kew but I assumed that as due to available space rather than it being 2 words.
Sadly, I don't speak any other language than Englush. But thank you for the recommendation.

I will have a look into the places yiu have all suggested. Thank you.

I really did enjoy that video. Thank you for sharing.

I managed to work out the town my Great Grandmother was from in the end. Zashkov, Russia (now Zhashkiv, Ukraine). The German spelling of the town was Saschkew which is what had caused the confusion. Thank you to everyone who helped me.

Russian Jewish? If so, JewishGen https://www.jewishgen.org/ is the best resource. They have loads of records which are not available elsewhere online, and discussion groups/forums with people who can help.
