How do you adapt a family tree to show divorce/remarriage?

There are many visual ways to show more than one marriage, in a chart form. The problem with decorative "trees" (using the term loosely) is that they can be very time consuming.
Most researchers who accumulate a lot of information wind up using a genealogy program, which is set up to deal with all those persons. The LDS church offers Personal Ancestral file for free, via website, http://www.familysearch.org. It remains a standard… you can include pics, etc. Almost all the standard programs offer "gedcom" ability… that is, transfer the facts to a file that is interchangeable with other genealogy programs. thus, if you really got hooked and decided that you want/ need a fancier program (read, buy it), you just transfer what you have to the new one.
Another standard is called a family group sheet… which lists husband, wife, and children, and includes a space for the parents of each spouse.. linking back to the prior generation. YOu would do a separate fgs for each marriage, but in the program, they would "link". These are just the basic facts… not so much as a biography type thing, which gives more of a personal touch.

good Question dont know

When you show it on paper it looks like

grandmother (name) = first husband (name)

– children (if any) year of birth

– children

= second husband (name)

– children etc.

you put 1st husband with symbol for divorce in one side then add the second husband to the other side with wife .

Leaving enough space for next generation.

Chainsaw?

This site has a lot of forms that would help.

Are you talking about in a genealogy program? If so, what program. If you’re just talking about on paper just list it as a 2nd marriage with all his info

She’ll just have two marriage lines with a mark across the one which ended in divorce. Children from each marriage will be placed in between her and their respective fathers.

i use family treemaker program – you have to buy it. It will show all the records you input & generate trees, reports & even a book – also you can add pictures, etc.
the form you mention to give to family members to fill out is called a pedigree sheet or chart.
for the story book – choose a theme such as
school memories, childrens games
how they met their spouse
travel/migration
what life was like 50 years ago
obstacles they overcame
careers, college, leaving home, parental relationships, raising kids, traditions – christmas, thanksgiving, birthdays, etc
regrets, mistakes and milestones.
be sure and ask for copies of old photos & the story about the photo.
