ŚLĘCZKA (the proper spelling) in Polish peasant dialect once meant a woman not invited to a wedding who would stand outside and peer through the window at the festivities. Maybe not a party-crasher but rather a party-peeper. The masculine equivalent is Ślęczek.
im also looking for some heritage details my great grandfather moved to Canada from Russia and his last name was Kapeluch but was changed to Capeluck which is my last name now but everything i've found leads me to believe its Ukrainian in origin is this correct?
Kapeluch - the augmentative* form of kapelusz (hat), is a bona fide Polish word. It came into Polish from middle Latin capellus. That does not mean that it does not also exist in Ukrainian. From a lingusitic standpoint, we cannot go beyond that statement. To determine the ethnicity of your ancestor, you would have to consult a professional genealogist.
* augmentative -- a grammatical form that makes something sound bigger, coarser or more overwhelming that the original; eg -- pies (dog), psisko (big, old, nasty cur).
