On the left, the 'father' is wearing a suit, vest with watch chain, tie, and I believe it's called a fedora hat.
Next to the right is his middle son, wearing his 'Sunday-Best' suit and a cap that has many different names: [A flat cap is a rounded cap with a small stiff brim in front. The hat is also known as a cabbie cap, longshoreman's cap, cloth cap, scally cap, Wigens cap, ivy cap, derby hat, jeff cap, duffer cap, duckbill cap, driving cap, bicycle cap, Irish cap, Newsboy cap, Crook cap, Joao's hat, Sixpence, or a Paddy cap and in regional varieties: in Scotland as a bunnet, in Wales as a Dai cap, and in New Zealand, as a cheese-cutter.] *whew* ...thanks Google-search!
He seems to have a tie pin just below his tie knot, a pen clipped into his jacket chest pocket, and something in his coat pocket, maybe a small book or tobacco pouch.
His left (on our right) thumb looks to be bandaged.
Next to him, on her bike, is 'middle-son's' wife, from the next-door farm, a mere 17 miles away. She seems unhappy to have to ride a bike to church, rather than her family hay wagon. But happy to be out and about for a few hours, rather than in the kitchen cooking and cleaning for the whole family.
To her left is her older brother-in-law, Poppa's oldest and biggest boy.
He might have a ring on his right index finger. ..not married yet, and more than a little jealous of his younger brother having a wife before him.
Behind him, and peeking out from behind the barn, is the youngest brother. He is sick, so he will miss going to church this Sunday morning.
Finally, there's Momma, standing behind her middle son and that woman he married. She is wearing a scarf to protect her hairdo, and is a little upset because she has to stay home to care for her little one, rather than go to church and visit with her neighbors. It looks like there might be a pipe stem sticking out of her dress pocket.
