Well...it's possible this is 1915, actually, but there isn't much to date. I'd really like to see the bridesmaids etc.
The bride is wearing a mobcap, which although more closely associated with the 1920s, was around in 1915ish, and it's (thankfully) a subdued low-profile one. Later ones looked like shower caps
.
Her dress is a full length formal style that wouldn't look out of place in any decade, really.
Second photo, I'd think 1940s.
Cheers,
