Growing up, I was friends and classmates with four girls from two families, who's parents both got divorced, and then later separately each married each other. In other words, father 1 and mother 1 divorced, and then later married mother 2 and father 2. Then each new couple had more kids.
Both sets of my grandparents (mom and dads parents) came off the boat in the early 1900's and worked the coal mines in Pa.
On my mom's side, my mom was the last of 5 kids when her father was killed working in the mines. After my grandmothers first husband died, she married another man who's wife died at age 33 due to a tooth extraction (infection, took some time). That man had 5 children of his own when he married my grandmother.
Instant family of 10, then they had my uncle as a son, family of 11.
Both sets of my grandfathers on my moms side died before the age of 50 before the year 1950 working in the mines (no OSHA back then).
Both my grandfather and grandmother on my dad's side died before 1955 (my dad's father died in the mines as well). He was one of about 10. My dad died in 2022 and he was the last of all of his siblings left alive at the time.
Different times...
Now a days, all bets are off how families "come together" LOL
What I can tell you is that raising 2 boys of my own in the last 20 years makes me wonder how in the heck you can raise a large family. That said, my dad being the runt, was picked to lite the fuse in the illegal family coal mine so they could have coal to heat their home. 14 year old girls were also cooks and dressed and took care of their younger siblings because parents didn't have time to.
As mentioned, different times...
I try to never forget what my grandparents went through even though I didn't know most of them (only grandparent I knew was my mom's mom). Family didn't have a pot to pee in and my parents made something of themselves. We take to much for granted now a days IMO.
