Can anyone help on looking for the above. Any hint will be appreciated. I have checked every possible record but because the are not complete I am never sure if that is the person I am looking for. Anyone willing to help me please look at my family tree for details.
Walenty Prusaczyk , Franek Prusaczyk emigrated to USA from Poland about 1920 +- 10 years.Fathers name Andrzej, mothers name Katarzyna , born Piasecznia Poland.

Can't seem to find your family tree.

Can you give some specific information here?

sorry I am very good with this site. I will write little story about my family.
My grandfather Konstanty(Constantine)born in village in Poland - Piasecznia. Father's name was Andrzej(Andrew) , mothers name Katarzyna (Kathrine). He had six brothers called: Josef(Joseph),Walenty , Antoni(Anthony) , Stanislaw(Stanley),Franek ,Piotr and one sister Rozalia. All the brothers emigrated to USA not long before WW1. Josef returned to Poland just before WW2 and was killed by Germans.
Stanley was killed in WW1. Walenty and Antoni had never returned to Poland so I believe they got married in USA and probably had children. If anyone know anything about it I will be very grateful. thank you.

Do you have birth dates for any of the brothers?

Here are a couple of possible records:

This one caught my eye because of the birth place:

Thanks guys for trying to help me out , really appreciated. Some of those sugestions I have already checked and not able to confirm dur to lack of date of births or places of residense. But some of them look quite promising , hopfully will take me there. Thanks ones again.

I'm sure that you know that this is an uncommon surname.

Have you tried general searches on Ancestry, including looking at the Family Trees? Also, the World War I Draft Registrations, and the Social Security Death Index?

Good luck!

Do you at least know the birth/death info on Konstanty? Where did he die? Who did he marry? Knowing his information helps narrow down an age range for the brothers.

Joy

There's more than one Antoni Prusaczyk. I found this newspaper article:

Canton Repository, Canton, Ohio
Friday, January 17, 1936
57 Foreign Born Passed in Tests
15 Nationalities Among Class to be Presented Papers of Citizenship
...57 foreign born residents of Stark county...successfully completed final examinations in citizenship...names and addresses follow...Antoni Prusaczyk of 1421 Frederick Ave. SW

There are at least two Antoni Prusaczyks:
