Genealogy / Kolodjiojryki / Kohodjiojryki; what ethnicity and meaning [5]

Can anybody help me. A grandmother in our family (on mothers side) was from Krotoszyn in Posen Poland, born in 1902. We are looking for any information about the name, ethnicity or meaning of her name. A cousin sent these spellings (Kolodjiojryki / Kohodjiojryki) from a document she has in her safe deposit box. She said she was not sure she had copied it correctly because it was hard to read. We know that Russia had control of this area at times... Not sure of the origins.
