There are only two Val Gasior's in Hamtramck and they are father and son. Valentine Gasior, Sr. was married to Pauline Wierzchowska, daughter of John and Mary. Valentine died in 1922 and is buried in Mt. Olivet Cemetery in Detroit. They lived at 3242 Evaline, Hamtramck, MI. Their children were:
Valentine (Val) born about 1910
Stanley (died in 1920 age 1)
Anna (perhaps your grandmother? Born about 1920)
Rose (died in 1912 age 7 mos)
Victoria (died in 1910, age 2 yrs)
Pauline died in 1969. She was best friends with my great grandmother who was also named Pauline). I have a photograph of them at my great grandmother's wedding from 1904 at St. Albertus Church in Poletown.
You may have some info turned around. Valentine, Sr. did have siblings, though. I recall seeing two brothers. I have not been able to locate any marriage license for Valentine and Pauline.
Contact me if interested.
