如何利用家谱树添加父母？

Question

我正在建立我家谱（包括所有远房亲戚）。我想添加我的曾曾祖母，她是我曾祖母的分支。我曾祖父的分支没有问题。这是一部分（祖母分支），举例来说：

\documentclass[a4,10pt,landscape]{article}
\usepackage{incgraph}
\usepackage[all]{genealogytree}

\newcommand{\f}{female}
\newcommand{\m}{male}

\gtrset{database format=short,edges={anchoring=center},language=spanish, level 0/.style={level distance=5mm}, level -1/.style={level distance=10mm},level -2/.style={level distance=15mm,level size=20mm, node size = 20mm},timeflow=down}
\gtrset{comment code={(\gtrDBcomment)}}

\begin{document}
\begin{inctext}
\begin{genealogypicture}[processing=database,database format=full,template=signpost,node size=3cm,level size=3.2cm,list separators hang,place text={\newline}{},box={fit basedim=9pt,boxsep=2pt,segmentation style={solid},halign=left,before upper=\parskip1pt,\gtrDBsex}]

{
    child{
        g[\m]{
            my great-great-grandfatherX
        }
        p[\f]{
            my great-great-grandmotherX
        }
        child{
            g[\m]{
                my great-grandfatherX
            }
            p[\f,processing=database]{
                name={my great-grandmotherY},
                comment={\textbf{Here!} How add her mother or father?},
            }
            child{
                g[\f]{my grandmotherX}
                p[\m]{my grandfatherZ}
                c[\f]{my aunt}
                c[\m]{my other uncle}
                child{
                    g[\f]{my other aunt}
                    p[\m]{husband of my aunt}
                    c[\f]{my cousin}
                }
                child{
                    g[\m]{my father}
                    p[\f]{my mother}
                    c[\f]{my sister}
                    c[\m]{my brother}
                    c[\m]{me}
                }
            }
        }
    }
}
\end{genealogypicture}
\end{inctext}

\end{document}

我尝试在其中使用父级：

   p[\f,processing=database]{
            name={my great-grandmotherY},
            comment={\textbf{Here!} How add her mother or father?},
            parent{
                    g[\f]{my great-great-grandmotherY}
            },
    }

不起作用，但至少没有显示错误。它几乎与 genealogytree 手册中 Gauss 家谱树的示例（第 39 至 42 页）相似，但我无法正常工作。

非常感谢！Darío
