I have this code that outputs a small family tree
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{trees}
\begin{document}
\begin{tikzpicture}[
man/.style={rectangle,draw,fill=blue!20},
woman/.style={rectangle,draw,fill=red!20,rounded corners=.8ex},
grandchild/.style={grow=down,xshift=1em,anchor=west,
edge from parent path={(\tikzparentnode.south) |- (\tikzchildnode.west)}},
first/.style={level distance=6ex},
second/.style={level distance=12ex},
third/.style={level distance=18ex},
level 1/.style={sibling distance=5em}]
% Parents
\coordinate
child[grow=left] {node[man,anchor=east]{Jim}}
child[grow=right] {node[woman,anchor=west]{Jane}}
child[grow=down,level distance=0ex]
[edge from parent fork down]
% Children and grandchildren
child{node[man] {Alfred}}
child{node[woman] {Berta}}
child {node[man] {Charles}}
child {node[woman]{Doris}};
\end{tikzpicture}
\end{document}
and what I want to do, is to write 2 lines of text in each box (e.g. Jim and underneath his DOB). How do I break a line in order to do that? \\
doesn't work.
Here is a printscreen of the output:
