Credits: altered background - Wishing for Spring; altered green & light green papers, swirl - Hello, Aunty; altered stitching - Mother May I; brad- Spa HolidayMy Grannie, Louise (Long) Brown, had a set of biological grandparents but she never knew them. They were only names on a paper. Her adopted parents' parents were William Lester and Sarah Angeline Long and Andrew and Emma Smith. Lester died when she was 4 years-old. Grandma Angie Long died when Louise was 10. Though she didn't share many memories of Angie, Louise had close ties to her Long aunts and uncles. The journaling on the Long page details the biographical nature of the grandparents and the closeness of Lousie to her aunts and uncles.
Grannie never her grandma Emma (Ward) Smith, but she has many memories of her grandpa Andrew Nelson Smith. Andrew was a barber and would cut Louise's hair when she was younger. Andrew also lived with Harry and Lura until his death in 1933. The following year, his daughter Lura Long died. Thus leaving Harry, Marguerite and Louise alone. Additionally, I mentioned the second marriage of Andrew Smith to Mary Etta Webb. Louise never mentioned her, only Emma.
As you can see with the journaling on these pages, you want to included stories whenever possible. When the stories are unavailable, you can share the biographical information in a story form.
As for design, these two layouts face each other in a printed book. The pages need to compliment each other. I chose a similar layout design and used repetitive papers to coordinate the pages.
My tips for grandparent pages is to stick to one page for a pair of grandparents. Unless your subject was born in the 1970s til now, the information and photos for grandparents will certainly be more limited than the 'photography' age.
