The blury image at left is Yvon Roy.
To his right and being held by a woman on a rocking chair is Henry Roy.
Seated on the rocking chair is probably Marie Jessie Bilodeau.
Standing behind her could be her daugther Cecile Gagnon who is the mother of the two boys mentioned.
This photo may have been taken in Quebec about 1929. We don't know exactly where in Quebec this was but it appears they were visiting a place like a church.
